I need to have a word with our canteen about the definition of 'square'

Emma Barnett : outstanding job on #r4today this morning

I absolutely love Don Steward But truthfully I am stuck Can anyone offer any advice on the property of the 3 digit numbers mentioned here?

My strong Year 7s need some practice on multiplying decimals by hand. I've been talking to our PGCE about injecting fun into a task -- so i've put together this Murder Mystery task I'll upload the editable .pptx later

Awesome roots task by @dandraper.bsky.social Also an excellent order of operations post here mrdrapermaths.wordpress.com/2017/04/08/o...

I saw someone the other day post something similar to this At the end of each question I have put hints as to what the marks on the mark scheme are for. I have done this for one of the Edexcel Foundation Mock Sets and think my group will find it useful as a scaffold. www.mrchapmanmaths.com/revision

I *think* my tarsia generator is working pretty well now. www.mrchapmanmaths.com/tools/tarsia... #MathsToday

Tool i'm currently working on School won't allow me to download tarsia software So i'm vibe coding a tarsia puzzle maker This is proving harder than other little projects i've worked on If anyone wants to test out what i've got give me a shout

GCSE Iteration Showing staircase diagrams to give students a sense of what is going on Can anyone think what disadvantages there might be of showing this at KS4? Do these outweigh the merits?

With @ox.ac.uk and @cam.ac.uk Maths courses now requiring TMUA for 2027 entry onwards it seemed a good time to remind you of the @meimaths.bsky.social TMUA On Demand course. Free for students from state-funded schools & colleges. Perfect to recommend to Year 12 students 😁 mei.org.uk/course/prepa...

In #MathsToday I got my Y7s playing with the Frogs Project from nrich For which I put together an applet for them www.mrchapmanmaths.com/algebra/frogs Featuring -> Campaign mode where they have to get the optimal solution before moving on -> Colour adjustable frogs -> Confetti cannon when you win.

#TodayInMaths Dijkstra's Algorithm! For which I have put together a digital tool: www.mrchapmanmaths.com/ks5/dijkstra Happy to hear feedback on it! Think I have worked out the major kinks.

Quick Sort! Including Custom lists and 'Edexcel mode' where the Pivot must be selected as the middle entry (or right of this if there is a conflict) If anyone can let me know how quick sort is done on other boards I can update it. www.mrchapmanmaths.com/ks5/quicksort #ALevelMaths #MathsToday

Edexcel QuickSort - students choose the central value as a pivot OR the right of the two if there are two central values. I heard a rumour on the grapevine it is the left of the two for AQA and different in other exam boards... Can anyone confirm/deny/clarify?

Bubble sort practice Including optional modes where you must write number of comparisons and swaps made And a 'manual stop' mode where you say when you want the sort to stop (i.e. after a pass made with no swaps). www.mrchapmanmaths.com/ks5/bubblesort #mathstoday #alevelmaths

Fun little game that I've played for years with classes and now available as a web app. -> Randomly generate a number 1-9 and place it in the column addition with a target of 1000 -> Option to swap a pair of digits, and to bin one you don't like. www.mrchapmanmaths.com/number/targe...

Wednesday's TGT takes a look at Rosa Parks. I hope many will know her story already. But it's interesting to note she wasn't the first to defy the racist segregation of Montgomery's buses, but civil rights leaders did think she was the right person to be the face of change. bit.ly/TutorGroupThink

Correlation ≠ Causation

Large Data Set revision flashcards -> Questions marked wrong or partially wrong will appear more regularly in future (memory of this stores locally) ->Option to review weak areas www.mrchapmanmaths.com/ks5/ldsflash... #MathsToday #ALevelMaths

I'll be the first to admit I have gone crazy creating digital tools using Gemini vibe coding BUT check out what i've been doing today: Edexcel GCSE Maths Foundation revision tracker. RAG rate the skills; you can then later filter by your RAG rating. www.mrchapmanmaths.com/revision/ede...

A relief to have passed my NPQLT!

Needed an isometric drawing tool, asked Gemini to write me one. Available here: www.mrchapmanmaths.com/geometry/iso... Includes: -Adjustable dot thickness -Editable spacing -Change dots to lines -Fill tool -Colours -Download button -Line thickness -Pan tool -'Box' Tool #MathsToday

Kruskal's and Prim's Algorithm tool available here: www.mrchapmanmaths.com/ks5/mst-algo... #ALevelMaths #FurtherMaths #MathsToday

3 exciting new opportunities to come and work with me @meimaths.bsky.social 😁 mei.org.uk/about/careers/

KS4 Foundation Bank the Basics Coded through Gemini -- the code is available via a button at the bottom of this page if you want to try adapting it through an LLM of your choice. www.mrchapmanmaths.com/bank-the-bas...

A great insight into a lack of understanding between leaders and employees on the impact AI is having www.wsj.com/lifestyle/wo...

Need some prompts to Check in / Check on / Check out with your form throughout the week? Here's a spinner I've made to generate prompts. Including: -> Think/Pair/Share timer -> Prompts for start/middle/end of the week -> Option to add custom prompts www.mrchapmanmaths.com/formspin

In #MathsToday I used the Nandos menu to help explain how to answer 'given that' probability questions. "What shall I order...given that I want a sandwich, wrap or burger?"

The awesome school I joined this September are hiring maternity cover starting in June this year. Get in touch if you have questions mynewterm.com/jobs/137288/...

Edexcel D1 Graph Theory Key Terms Match-Up for Chapter 2 Now available on my site i'm building up here: www.mrchapmanmaths.com/ks5

National Careers Week coming up and we need to deliver a 60 minute lesson on careers-- anyone got anything good they have used in the past ?

Just getting to grips with building a website so excuse the state of it But i've built this Graph Theory Key Terms connect the dots using vibe coding (thanks @harryzafar.bsky.social for all of your work in this area). About 50 mins worth of work. www.mrchapmanmaths.com/blank-3 #MathsToday

I am absolutely staggered by the quality of Gemini to write code for tools now. In about 20 minutes I generated this percentages of amounts tool through a conversation with Gemini. I know there are SUPERIOR tools to it but this is proof of concept. www.mrchapmanmaths.com/blank-2 #MathsToday

A colleague has been using this game on Bitesize for a low attainment Y7 group. Aimed at KS2 but still quite nice. www.bbc.co.uk/bitesize/top... Free on Bitesize-- allegedly it saves progress and adjusts difficulty based on performance.

Marbleslides will never not be fun. #MathsToday Activity here: classroom.amplify.com/activity/589...

Merry Christmas to all of you and your loved ones.

Crazy data ffteducationdatalab.org.uk/2022/05/does...

Bored over the festive season? We're still seeking contributions to our ridiculous saytheprime.com video project: sign up and make a 5-minute video of yourself saying a chunk of digits of the largest known prime number. Can we finish before they discover a bigger one? It's a race against maths!

Has anyone got any insights on teaching of Decision maths? In a perfect world a scheme of learning would be great- or at least an insight into important orders / things you can't do before other things! #ALevelMaths

What one doesn't belong and why? Can you give a reason for each Starting some geometry with Y7 Led to a lovely conversation wondering if two curves can be parallel #MathsToday

Enjoying this from a 1947 exercise book

Anyone else had a spurt of 100 odd accounts that are clearly bots follow them?

Compilation of matrix proof by induction questions Downloadable pdf / editable .pptx here mrchapmanmaths.wordpress.com/2025/12/04/p...

Ever since Tom Dean’s killer presentation at #PiXLMaths conf on Tuesday, I’ve been obsessed with those sticky math mantras that make exam answers pop! What’s missing? Share your memorable nuggets of wisdom for crushing questions. #ExamTips 🚀 @mathsjem.bsky.social

I've seen something like this before but can't find anything on it so i've put this together - GEMs assessment review. Ss review their assessments identifying the nature of their errors Gaps in knowledge Exam technique Misconceptions Going to try this with Y11 following mocks

After PiXL conference yesterday I have been thinking about exposing students to mark schemes and getting them to be in the shoes of an examiner more often. Here's my dodgy solution to a CP1 series question, i'll give it to my class to mark and spot the mistake(s). #mathstoday #furthermaths

Absolutely rinsed the mini today I solved the 11/17/2025 New York Times Mini Crossword in 0:13! nytimes.onelink.me/IM32/7owuagxr
