5 Maths Gems #190

Welcome to my 190^th gems post. This is where I share some of the latest news, ideas and resources for maths teachers.

1. Resources Created Using AI

I posted about @DGRAIMaths's resources in my post AI Maths Resources last year. His website aimaths.weebly.com has now been updated with a new set of resources covering histograms, cumulative frequency graphs, box plots and line graphs.

Duncan uses ChatGTP to help him make these resources but he doesn't just type in a prompt. The AI generates graphs and questions but it's Duncan who does the thinking about what the tasks should actually look like. The resources follow an "I Do, We Do, You Do" approach, intended to be delivered at pace, with live modelling leading to lots of independent practice.

Duncan's aim is to break down each topic so that lower attaining students can access high level material, and to create resources that can be used by non-specialist or inexperienced teachers.

In these resources Duncan has stripped away unnecessary complexity - things like awkward language or overcomplicated scales - and introduced key representations without context at first, so students can focus on the mathematical structure without distraction.

Check out Duncan's resources at aimaths.weebly.com.

2. Dr Austin's Key Stage 3 Revision
I really like these new Key Stage 3 revision resources from Dr Austin. The worked examples at the top means they'll work well if you're setting cover for absent teachers, as well as for revision.

3. Best Guess GCSE Papers
Many thanks to everyone who has created and shared Paper 2 resources for next week's GCSE exam. These include @1stClassMaths, @MathsTeacherHub, @Mr_D_Does_Maths, @hkettlemaths, @ThtPedagogyGeek, @CorbettMaths, @OnMaths, @ThirdSpaceTweet, @MattTheApp, @GCSEMathsTutor, @Just_Maths, @AddvanceMaths, @BennettMaths and @DrFrostResource and more (apologies to those I've missed - there's been so many to keep track of!).

1stclassmaths.com

At my school we are fortunate that we have no GCSE exams the day before Maths Paper 2 this year and we have a couple of hours where all the Year 11 maths teachers are available, so we've invited Year 11 into school to do some predicted papers that day. We plan to use the 1st Class Maths Predicted Papers plus a revision mat that I've made containing topics that might come up in the exam the next day. If you want to borrow this revision mat (note that we do AQA), feel free to download it here. Please note that I don't take any credit for writing most of the questions - I've just found questions that my students haven't seen before and arranged them in a useful resource. It's designed to be printed on A3 to ensure there's some space for workings. I've also made similar A level revision mat (we do Edexcel at A level) for our pre-exam warm up next week that you're welcome to borrow if you want.

4. GCSE Statistics

Since I started teaching GCSE Statistics as an option block course I've realised that there's a huge gap in the market for resources for this qualification. There are plenty of resources available for GCSE Maths, A Level and AQA's L2 Certificate in Further Maths, but high quality resources for GCSE Statistics are seriously lacking.

However I'm delighted to see resources for GCSE Statistics are starting to appear. This summer I hope to add a GCSE Statistics section to my resource libraries so I can signpost teachers to tasks for each topic. If you've produced GCSE Statistics resources that you're sharing for free, do get in touch so I can include the links in this new resource library.

In case you haven't seen it, statsgcse.com is a new website from OnMaths which has practice papers that students can complete online.

In my last post I mentioned @harryzafar's new website mathboardwalk.com. This collection of resources continues to grow, for example the latest addition is a resource for teaching Normal Distribution. 

@karenshancock has also shared a second GCSE Statistics revision paper at kshancock.co.uk.

5. Alpha Books
Thank you to ‪@neechmaths.bsky.social‬ and ‪@mrsevcartwright.bsky.social‬ for pointing me towards the temporary website alphaworkbooks.co.uk from Phil Thorns. Phil has published a collection of write-on workbooks which include examples, questions, hints and answers. These workbooks are great - a lot of the tasks have scaffolded hints, so I can see loads of potential uses for them, including cover work, revision and homework. 

Sadly the company Alpha Workbooks is closing down but Phil has very kindly decided to offer the workbooks to students and teachers for free. Download them quickly before the website is taken down! There are workbooks for both A level (including both statistics and mechanics) and GCSE.

Update

Exam season is underway. I have eighteen exam warm ups to prepare and run this year, and I've only done seven so far, so we still have a long way to go! It's all good fun though - I love the summer term. And there's so much to look forward to when exam season is over. I always have a great time at the MEI Conference and I can't wait to attend again this year - I will be there on the Thursday night and all day on the Friday. Book a place at mei.org.uk/conference.

I'll also be at #mathsconf38 on 21st June, presenting on some lovely surds and algebra from old textbooks. I won't be there for the pre-conference drinks on Friday night though, because I'll be in London at the TES Awards (my lovely school is up for a technology award and they are kindly letting me tag along at the awards event!).

Our friends at Casio are keen to receive feedback on their new fx-CG100 so please do let them know what you think. They have various videos to help teachers learn how to use this new model.

In other news, Craig Barton and I are thinking about running another course this October: Marvellous Maths 4. Those of you who have attended before will know how this works: it's a full day of CPD for maths teachers, and we hope to run the same event in three separate venues: South, Midlands and North. We have really enjoyed running these courses in the past and we always get great feedback. If you can offer a suitable venue in the Midlands on 21st October 2025, please get in touch (e.g. a school with capacity for 100 delegates and good transport links). 

I'll leave you with two things that made me laugh. First, from 1stClassMaths, part of a question in a practice paper with a joke that I thought only people of a certain age would notice, but has been getting lots of attention from students on TikTok:

And some Star Wars maths jokes (see this thread), which were shared on May the 4th.

5 Maths Gems #189

Welcome to my 189^th gems post. This is where I share some of the latest news, ideas and resources for maths teachers. As exam season is fast approaching, there's a revision theme in today's post!

1. MathsPad 

It's always great to see new resources on my favourite website MathsPad. In March they published a number of new tasks including GCSE revision worksheets. 

This includes Foundation Tier worksheets on fractions, ratio, angles, indices and so on.

They have also shared a couple of excellent 'Mixed Questions for the Day Before' resources - one for Foundation and one for Higher. 

You'll find a link to MathsPad GCSE revision worksheets on my GCSE Revision Resources page which always gets a lot of visits at this time of year! I constantly update this page, for example I've recently added resources to help students practise using the formula sheet. For quick access to this page, at this time of year you'll find a link at the top right of my website.

One thing that I don't do on my revision page is link to the new 'best guess' papers that are published each year. There's no point in me replicating work done elsewhere - you can find links to these resources in Adam Creen's Dropbox. Thank you Adam! These resources become particularly important between GCSE papers. We can't predict what's going to be on Paper 1, but we can make some good guesses about what's left to test when it comes to Papers 2 and 3. Speaking of Paper 1 predictions, make sure you watch this 1st Class Maths video about the 'five year rule'. There are lots of companies trying to make money out of our students. It's important that we provide students with an abundance of free revision resources so they don't spend money unnecessarily.

2. Dr Frost

The team at Dr Frost have been busy publishing lots of resources recently. Something new that caught my eye are the Building Blocks tasks. These one-page worksheets for a number of different topics are designed to strengthen key skills, gradually building towards interleaved problem solving. They come in different GCSE grade levels (Grades 1 - 3, Grades 4/5 and Grades 6+). Here are a few examples of the Grade 6+ resources. 

3. GCSE Statistics

Given that this qualification has relatively few resources, it's great to see new revision tasks for GCSE Statistics.

Thank you to @benrooney for sharing a revision mat for Higher GCSE Statistics (answers here). 

Thank you to @karenshancock for sharing Higher GCSE Statistics revision papers at kshancock.co.uk.

Thank you to @harryzafar who has shared loads of resources for both Foundation and Higher GCSE Statistics on mathboardwalk.com including worksheets and revision grids.

4. A Level Revision

Thank you to Dr Bennison and Emily Rae who have both shared new revision resources for Level 3 qualifications. 

Tom Bennison plans to release a number of resources on his website. His first set of resources are seven worksheets of AQA Further Maths AS Questions. Thank you Tom!

Emily has shared the following resources here:

• editable warm up grids for AQA AS Further Maths (pure and discrete/stats options)
• an editable warm up grid for AQA A Level Maths Paper 1 
• updated revision grids for AQA Core Maths (Paper 1 and 2A). 

Thank you Emily!

5. 3D Pythagoras

I enjoyed this idea for teaching 3D Trigonometry from Andrew Stacey. He gave his Year 9s this diagram. He picked numbers for a, b and c and their task was to work out all the lengths and angles. In the next lesson they cut it out and assembled it, discovering that they've secretly been doing 3D trig!

Update

A new graphical calculator came out last week (the Casio CG100) and I'm very grateful to Science Studio for surprising me at school by sending one in the post on the day it was launched (engraved with Mrs Morgan, which I love!). 

In case you missed my last post, I shared some GCSE and A level revision resources that I made over Easter.

La Salle shared the locations of their upcoming conferences:

• #mathsconf38 is on 21st June at Ormiston Sandwell Community Academy in Dudley
• #mathsconf39 is on 11th October at Harris Academy St John's Wood in London

Exams are coming round so quickly now! It might be time to put up the meme posters (see Gems 167) to lighten the mood...

New Revision Resources

This is just a quick post to share a couple of revision resources I've recently made.

I'm delighted that the Easter holidays have arrived but I think I'll need to spend a bit of time over the break creating new revision resources to use this summer. My school opened seven years ago so this is the first time we'll have A level exams. And we've been running our new option block course (GCSE Statistics and L2 Further Maths) for two years so we have those exams for the first time too. I have responsibility for running revision and exam warm ups for sixteen exams this summer....! For Year 11 that's three papers for GCSE maths, two for GCSE Statistics, and two for Level 2 Further Maths. For Year 13 it's three papers for A level maths and four for A level Further Maths. Plus our Year 12s take AS Further Maths too, so that's another two. Some of these exams are even happening on the same day which seems a bit inconsiderate of the people who write the exam timetable! It's going to be a very busy term with all the exam warms ups and revision sessions and everything else going on. Exciting times though. I love the summer term!

GCSE Maths
For GCSE there are already an incredible number of revision resources available. The qualification is well established and there are now so many resources it can feel a bit overwhelming - see my GCSE revision page for lots of examples. We don't need to make GCSE breakfast warm ups because we have the warms ups I made back in 2018 - we always find that these work really well. The main new resources we need every year are the 'best guess' papers and checklists that are made between exams - they are really helpful and I very much appreciate the people who make them (I particularly love the papers produced by 1st Class Maths) - I know it takes a lot of effort on tight deadlines. This year there aren't any GCSE exams on the day before Maths GCSE Paper 2 so this has worked out well - it means we can invite Year 11 in to do a 'Predicted Paper 2' session that day.

I had a double Year 11 lesson last week where I wanted to do something a bit different. We'd already been doing topic-based revision lessons for four weeks. After Easter I plan to move to mainly mixed-topic revision lessons (a mix of exam papers and revision mats). But for the last lesson of the Spring term I decided I wanted to do a quiz, so I made one. It's here if you want to borrow and adapt it.

This version was made specifically for my Set 5 class which is our lowest class on the Higher Tier. The students in this class should (fingers crossed) get a Grade 5, 6 or 7 this summer. The quiz starts very easy but gets harder. There are fifty questions and most of my students scored in the thirties, although the winner scored 49 out of 50. This quiz could easily be adapted for a Foundation class (my colleague Will has done this - his version is also here) or for a GCSE class working at higher grades. There are plenty of quiz questions to choose from on my 'Things to Memorise' resource.

There are a few different ways you could use this resource. Students could work in groups and write their answers down on paper and mark them at the end. I don't know if this is the most effective approach in terms of maximising their learning though. We want every student to use their brain to try and remember facts, and if they are in a group with someone who is very quick then they won't have the opportunity to do this. So doing the quiz in teams might make it a pointless exercise for the slower half the class. Instead, I ran it individually - students wrote their answers on mini whiteboards and showed me when instructed. This meant I could see and respond to common misconceptions, and I could make quick, subtle, individual corrections where needed. The questions lent themselves well to mini whiteboards as they were mostly one word answers. After each question I showed the correct answer and added some commentary if needed, and students kept a tally of their score on the back of their mini whiteboard. At the end they wrote their total score on their mini whiteboard to show me. Overall they really enjoyed the quiz and I felt like it went well. It took about 40 minutes.

A Level Maths

I wish there were more A level revision resources around! We had so many for the old C1 - C4 specification but there's not quite so much available for the new specification. It doesn't help that A level resources for one exam board can't necessarily be used with another board. During the Easter holidays I'm running a 2.5 hour statistics revision session for Year 13 and I had to make the session from scratch which took ages! At least I will be able to reuse it in years to come.

One thing I made that I thought might be worth sharing is a Statistics Quiz. I plan to use this for my starter in my Easter revision session. I made a load of revision quizzes for the old A level about ten years ago but they're all out of date now. So this is basically an updated version. I also made a Pure Quiz which I might use in June as part of an exam warm up, alongside some exam style questions.

I haven't tested either of these quizzes yet so there may be errors, but feel free to borrow and adapt (the files are here), and please let me know if you spot mistakes.

Update

While you're here, a couple of quick notices:

• I still have a maths teacher position available on my lovely team. This is a fantastic opportunity to teach maths at Key Stage 3 and 4 (and A level if desired - Year 12 or 13 or both) at a really fantastic school. Our GCSE maths results are brilliant (we are a totally non-selective school and half of our students get a Grade 7+ in maths) and our students have fantastic behaviour and attitudes. If you live in South London/Surrey then please get in touch (I'm happy to discuss the role or show you round - email me at resourceaholic@gmail.com) or apply directly by 22nd April. Come and work at a school where it's an absolute pleasure to teach maths!
• I'll be at the MEI Conference this summer. It's on 3/4 July at the Keele University. If you've not been before then do ask your school if you can attend - it's fantastic CPD and if you teach exam classes then the timing works well - you might not need much cover. The MEI Conference is always incredibly high quality and is quite different to other conferences, so if you've not been before then I really recommend coming this year. Hopefully I'll see you there.

That's it from me. Enjoy the Easter break!

5 Maths Gems #188

Welcome to my 188^th gems post. This is where I share some of the latest news, ideas and resources for maths teachers.

1.  Mr Chapman Maths
Thank you to ‪@dalechapman.bsky.social for sharing some great new scaffolded resources.

The first one is a backwards faded task for recurring decimals. The scaffolding makes the topic highly accessible - this task could be used before students start constructing full recurring decimal proofs from scratch. 

A downloadable PDF and editable PowerPoint are available on mrchapmanmaths.wordpress.com - I have added this link to my resource library. 

Another of Dale's new tasks is on calculating pie chart angles - again, there's some excellent scaffolding here. I've also added this to my resource library.  Thank you Dale!

2. 3D Trigonometry
I really like these 3D Pythagoras and Trigonometry tasks produced by @tiredoldcliche.bsky.social. The triangles draw students' attention to what's going on in these questions and encourage careful thinking. 

These tasks can be downloaded here and here. I've added them to my resource library. 

3. Year 6 Knowledge Organiser

Year 6 teachers (and parents of Year 6 children like me!) will find this helpful - @missjessrennie has shared a high quality Year 6 Maths Knowledge Organiser, including a quizzable 'fill in the gaps' version. 

4. Sequences

Arithmetic sequences are full of opportunities for reasoning. I like this set of questions from @catrionaagg.bsky.social‬. 

5. A Level Resources

Thank you to @draustinmaths.com‬ for sharing some new Year 2 mechanics resources for teaching moments at draustinmaths.com/a-level.

Colleen Young's most recent blog post about A level revision resources pointed me in the direction of Swinton Maths where I browsed through some great resources. For example there are some tricky Venn questions, a hidden quadratics fill in the blanks and some Further Maths practice papers. Thank you @mrsmaths.bsky.social. 

On the subject of A level - our Year 13s will get their mocks back next week and I'd like to give them a few minutes of quiet reflection once they receive their papers. I used to use a '5 Minute Mock Paper Analyser' with Year 11 (for more about this read these posts from many years ago: Y11 Post Mock Exam #5minplan: Pupil Self Evaluation and 5 Minute Mock Paper Analysis). Based on this idea I decided to make a Year 13 Mock Exam Reflection on Canva. I'm not the best at design and it's far from perfect but Canva is super easy to use for things like this.

This is how it might look when completed:

Job Vacancy

All the job vacancies I've advertised over the last six years have existed because we're a new school - naturally we've needed to recruit every year as the school has grown. We're a happy team and my school is a great place to work so we've had no turnover in the maths department. But now one of my teachers is leaving us for an adventure (teaching overseas), and this presents an exciting opportunity for a maths teacher to join my lovely team. This opportunity is open to anyone from ECTs to experienced teachers. It starts in September and it's based in South London. If you want to chat about the role please get in touch. We're looking to appoint before Easter so apply quickly!

I'll leave you with this which was tweeted by @MathMatize. How would an integral symbol wear a tie...? My children were discussing a similar question regarding a giraffe wearing a bow tie recently.

#mathsconf37

Yesterday I spent the day at #mathsconf37 in Sheffield. I've attended over thirty of La Salle's Saturday conferences since September 2014. They are regular fixtures in my diary (they take place in October, March and June) - I always make the effort to attend when I can. I think it's massively important that I keep developing my teaching skills throughout my career, and actively take steps to improve my subject knowledge and keep up-to-date with what's going in in maths education. I genuinely think that attending these conferences makes me a better teacher and a better Head of Maths. I also like the social aspect. Having made a few friends from attending mathsconfs over the years, I always enjoy catching up and chatting about maths teaching with them (shout out to Megan who I often share train journeys with, and David who very kindly gives us lifts). #mathsconf37 was definitely one of my favourite mathsconfs. Even though I live far away in South London, Sheffield is a great location (a straightforward two hour train ride from St Pancras and plenty of cheap hotels to choose from), and the school itself worked really well (I marvelled at the wide corridors, well maintained toilets and double size classrooms). Thank you to Head of Maths Ben Rapley for hosting.

I used to write blog posts about every conference I attended, and back when Craig Barton used to attend, I sometimes did post-conference podcasts too. I haven't done that for a while, but I wanted to write a quick post today to share a couple of things from yesterday's event.

I enjoyed all four sessions I attended. In David Martin's session on Platonic Solids I learnt an interesting fact about the colours on Rubik's Cubes - if you add or extract yellow from any side you get its opposite (more on this here).

white + yellow = yellow
red + yellow = orange
blue + yellow = green

I loved Rob Eastaway's session where I learnt loads of interesting stuff about the Elizabethans' use of numbers. And in Sam Blatherwick's session on Magic Multiplication Squares I did a lot of fun arithmetic and thought hard about grids, ratio and factorising.

In Matt Man's workshop I tried some lovely surds problems and also discovered some new places to find questions. I write a lot of Key Stage 3 assessments every year - it's one of the most time consuming things I do, but I do enjoy it! - and I often struggle to find interesting questions that students haven't seen before. For example for my highest attainers I want really challenging questions with lots of reasoning. And for my lowest attainers I want accessible questions with scaffolding. I use various sources to find questions but I always want more! Matt showed us that on Exam Wizard (which is free to use, as long as you have an Edexcel login) you can choose 'Awards' from the first drop down menu in 'Build a Paper' - there are a whole load of maths questions there that I've not used before. I was vaguely aware of Edexcel Award qualifications but I didn't think to look in a whole other section on Exam Wizard. 

They have everything from Level 1 Number and Measure which has plenty of questions suitable for Key Stage 3 assessments, to Algebra Level 3 which has lots of challenge. There are also loads of statistics questions (including topics such as binomial, normal, index numbers, moving averages etc), many of which will be useful for teaching GCSE Statistics where there's a serious lack of available resources to use in lessons. Here are some example questions from the various different awards:

Note that the last question here is not a surds question - this is just substitution so it's suitable for Key Stage 3.

Thanks very much to Matt Man for sharing this hidden source of questions on Exam Wizard!

At the end of the day I delivered a session on factorising. I shared some interesting questions and techniques from a 1914 textbook. Here are some examples of the kind of expressions we were factorising in this workshop:

The delegates really got stuck into these and I think the session was well received, so I might do a follow up at the next conference.

Thank you to La Salle for hosting a great conference, to Rob and Leonie for running a lovely tuck shop, and to all the speakers for their sessions. 

See you all next time.

Securing a Job as a Maths Teacher

The job market for maths teachers is particularly busy between January and May. Many of my readers might be in the process of applying for jobs and going for interviews. I sometimes get emails asking for advice so I thought it might be helpful to share some general advice here. I wish someone had told me these things in my first few years in the profession! 

Here's a list of fives dos and fives don'ts when applying for jobs in maths education.

Five things you should do

1. Do ask for clarification regarding the lesson

I once went for an interview where they simply told me to teach 'percentage change'. I fretted about what this could mean. Using multipliers to increase and decrease? Or working out the percentage by which something had changed? I didn't ask for clarification on the topic or the students' prior knowledge or anything else. On the day of the interview I taught a lesson on percentage change and quickly discovered that the students already knew how to do all of it. And even worse, all the tasks I had planned required a calculator, and no one in the room had a calculator...

I now know that it's totally standard to ask the school for clarification regarding the interview lesson. Most candidates email the school to ask for:

• Seating plan
• SEND information for the class
• Attainment levels, to help you pitch the lesson appropriately
• More information about the topic (e.g. if asked to teach a lesson on volume of a cylinder, ask whether the students have already studied volume of a prism etc).
• Equipment available, if relevant (e.g. whether students will have calculators, or whether mini whiteboards are available etc).

Some candidates ask for even more than this, and that's absolutely fine. I wish someone had told me earlier in my career that it's alright to ask for more information.

2. Do communicate formally

I know it sounds silly to say 'use capitals letters and punctuation on your application form and in emails' but you'd be surprised... If you're filling in an application form and you don't even capitalise the names of the schools you've worked in, it screams 'can't be bothered'. 

3. Do ask for a visit or a chat before applying

This isn't essential at all, but is totally acceptable if you're unsure about applying, particularly for big job changes where it's really important to get the right choice of school and understand the scope of the role (e.g. applying to be Head of Maths). And if you have questions about suitability, for example if a role has been advertised as full time and you want to know whether they'll consider a part time applicant, just email to ask.

4. Do ask about behaviour policies

If you're given a tour of the school on an interview day, look closely at the behaviour and attitudes of students in classrooms, corridors and playgrounds. In the interview, it's sensible to ask about behaviour policies and routines (depending on the school, I'd personally be looking for centralised detentions, sensible classroom escalation procedures, and a team of behaviour mentors or equivalent).

5. Do know how it all works

Teaching is a bit different to other industries. There are some fairly standard rules and procedures in recruitment.

• For safeguarding reasons references are taken before interview. So you have to tell your current headteacher that you intend to apply for a job before you submit your application (both as a courtesy, and because they will find out when the reference comes through anyway!).  
• The recruitment process tends to work very quickly in teaching so if you're asked to come in for interview then you'll normally only be given a few days notice. You'll have a very busy time preparing for interview, planning your interview lesson and setting cover. Don't try to negotiate the day of the interview - your current school shouldn't be asking you to do this. Obviously the school you've applied for will have already planned out all the logistics of the interview day and will want to see all the candidates at the same time. You shouldn't demand a change to the interview date unless you have a really good reason (like you're going to a funeral, it which case it's totally reasonable to request a different date). 
• Offers are normally made same day, and the expectation is that you'll accept or reject the offer straight away. This is because the school is waiting to inform the other candidates of the outcome. Make sure you're ready to make the decision when the call comes in. Or, if needed, tell the school you need to talk it through with your significant other/parent/friend and then phone the school back as soon as you've made your decision. Don't mess them around - it's not fair on anyone involved. I once offered to a candidate who accepted and later changed her mind (because her school made a more lucrative counter-offer) - but at that point we'd turned down the other candidates. So she left us with no one and we had to start the process all over again.
• Time is precious in teaching. Don't go for interviews 'just for the experience' if you have no intention of accepting the job. It's not fair to waste people's time. And once you've formally accepted a job at one school, make sure you withdraw any outstanding applications at other schools. 

Five things you shouldn't do

1. Don’t feel the need to show off every teaching technique in one lesson 

To me the most important aspects of an interview lesson are:

• a well structured lesson
• clear instructions issued to students throughout
• clear modelling and explanation (this is probably the most important thing!)
• at least one well chosen task [be prepared! - make sure you've got something ready in case the students are much quicker or need a lot more challenge or a lot more scaffolding than you expected]

I'd also want to see some kind of assessment of students' understanding, but you don't need to show off multiple assessment techniques in one lesson! Bear in mind that mini whiteboards can be tricky with a class where you haven't embedded routines. 

You can't demonstrate everything you know about teaching all at once. It's hard to show your very best teaching with a class you've never met before. Unless there's a large number of excellent candidates, a solid lesson is all that's needed. 

2. Don't worry about behaviour being a challenge in an interview lesson

Depending on the school, you might have to use a few techniques to get students on task, but if you have the Head of Maths and Headteacher sitting at the back observing, students shouldn't be disruptive. And if they are, the members of staff in the room will intervene (obviously you won't be expected to give detentions or send students out during an interview!). Schools normally pick 'nice' classes for interview lessons, so don't stress about this.

3. Don’t use recruitment agencies

They charge schools extortionate fees. This money should be going towards children's education, not into agents' pockets. If you're applying for permanent teaching roles then go directly through the school or MAT, unless there's a good reason not to.

4.  Don't turn up unprepared. Or late! 

Make sure you've practised answering some standard interview questions (you can find lists of these all over the internet - I'd print some questions, write out possible answers and practise saying them out loud). And don't worry about arriving very early and waiting in reception for a while. That's way better than misjudging the journey and arriving late.

5. Don't be scared! 

If you're unhappy in your current school then go for it - apply somewhere else. For example you don't have to put up with a school where leadership do nothing to address poor behaviour. I promise you, there are schools where teaching is a pleasure. They do still exist. Applying for a new job is difficult and time consuming, and it can be a bit terrifying, but if you're unhappy at work then of course it's absolutely the right thing to do. 

I hope this is helpful! If you're going through this process for the first time, make sure you ask for advice if you're unsure about anything. And if you don't have colleagues you can ask, try asking on Twitter or Bluesky where I'm sure lots of teachers will be happy to help.

Good luck!
