In each diagram, the green area and blue area are equal

For anyone interested, I've uploaded one of our booklets for sharing (Unit 1 : Points and Lines) but this is still a work in progress to some extent! sxpmaths.wordpress.com/wp-content/u...

colleenyoung.org/2026/06/28/e... Thank you @piximaths.bsky.social for the latest addition to the end-of-term activities collection.

Saw something recently about AI making an incorrect quadratic graph. Gave me an idea to use AI to create "common sense" check questions. Students often don't check if their answer makes sense. I try to embed this in my teaching, this will help. Started with quadratics #mathstoday shorturl.at/Y7jfq

proportion and ratio tables #maths

I got carried away and made a thing... Testers welcome! #alevelmaths #mathstoday #alevelrevision #mathsrevision

The more you stare at this, the worse it gets. Going to ask students how many faults they can find with it!

Thought this might be worth a reshare for people having conversations with year 12s about university applications. A spreadsheet of UCAS data by STEM subject (tabs along bottom) showing published entry criteria, most common grade profile and lowest grades of students accepted on to the course. 1/2

I'm already planning for September... a first. My new first-year IB AA SL students will be welcomed back with this task on equations, graphs and gradient. The idea is to tease out how they think as a mathematician and set us up for some work on straight line graphs. #MathsToday

In #MathsToday we used some of "Tyler Tutoring"'s TMUA preparation materials. I chose the pack themed around circles (second half of Coordinate Geometry Worksheet 3). A good mix of problems www.tylertutoring.com/tmua

I was making a worksheet for my student on areas between curves and came across beautiful questions from O-level AMath prelims. Good stretch material for your A-level. #ALevelMaths

Some start of Y13 content algebra revision/check for understanding resources I have used that may be useful for others. Functions, Partial Fractions, Modulus. Worked solutions given by clicking the questions. sites.google.com/rodingvalley... #ALevelMaths #mathstoday

Some new inequalities resources added to the site now: ✨ harder solving linear inequalities practice strips ✨ forming and solving linear inequalities practice strips Download word or PDF version, plus answers! Find them at www.draustinmaths.com/equations-and-inequalities #UKMathsChat #MathsToday

A couple of questions for the final day of my #calculus class. The hexagon question was from a post at the other place by Henk Reuling. I added the square version as a simplified option. #ITeachMath #MathsToday

🧮 Final Day of Calculator Crunch Four digits. One rectangle. A hidden pattern. Can you find the common factor? 👉 Take on the final challenge: buff.ly/U28kl5a #CalculatorCrunch

Looking at mathematical structures at @ncetm.bsky.social Secondary Mastery specialists course in Reading with @learningmaths.bsky.social

In #MathsToday we practiced differentiating polynomials before moving on to start looking at determining if a function is increasing, decreasing or stationary at a point.

In #MathsToday, I used this excellent standards units matching task to help students qualitatively describe cumulative frequency charts -- something I myself find quite difficult to do. Do people have "instinctive" ways to look at these, which can be shared with students? #ALevelMaths

In #mathstoday my son has asked me for some challenging OCR Add Maths #fsmq questions in prep for tomorrow - all I can find are past papers, and he's done them all. Anyone know of anything please?

✨New✨ algebraic direct and inverse proportion added today - practice strips and crack the code. Freely available at www.draustinmaths.com/direct-and-inverse-proportion #UKMathsChat #MathsToday

This was my starter yesterday to get pupils to appreciate the importance of the centre of rotation. And for the impossible one, why we also need translations. #MathsToday

"Your calculator is broken and will no longer do trig calculations. cos(1°) = 0.999848 to 6sf. Calculate cos(7°)." #MathsToday #ALevelMaths #ITeachMaths

Some polars students should be able to sketch on Edexcel Downloadable here; www.mrchapmanmaths.com/ks5

Marmite? Love it or Hate it? I'm collecting some (unserious) data for teaching purposes. If you have a spare minute, please fill out this anonymous opinion poll for me: forms.gle/M5C91iQxiWYC... It is a short list of (likely) polarising preference questions.

We didn't have power all afternoon at school. Luckily, you don't need power to arrange these definite integral dominos into a circle. A great way to start #calculus class. Thanks for sharing @math-problems.bsky.social! #ITeachMath #MathsToday

In #MathsToday we're having fun with proof by induction. Towers of Hanoi (interactive here: towersofhanoi.info/Play.aspx) plus this interactive version of the L-tiling problem I vibe-coded this morning: ukr-reader.github.io/MathsApps/l_...

Had a thought provoking question to start #calculus class last week. Students are practicing area between curves but when I asked them to optimize the distance between curves they had to really stop and think about the problem solving strategy. Inspired by ssddproblems.com. #ITeachMath #MathsToday

New! My 199th gems post. Ideas, updates and resources for maths teachers. 💎 www.resourceaholic.com/2026/06/5-ma... Hat tips to follow. #ukmathschat #mathstoday

In #mathstoday using gained time to start thinking about #Alevelmaths yr 1 summer work - do you do this and if so what? I was wondering about something on the large dataset but maybe that’s best done closer to exams? Or some yr 1 consolidation? Open to ideas!

🧮 Calculator Crunch is back! Free daily maths challenges for Year 6 (P7) and Year 7 (S1), designed to build confident calculator use and support transition. 📅 15–19 June 🏆 Win maths resources or a class set of Casio fx-83GT CW calculators 👉 buff.ly/bGYNFAU #CalculatorCrunch

Problem of the Week 175! Please do not comment the solution so others can work it out too. Instead, like this post or comment a thumbs up if you think you have the correct answer! The solution will be posted in the comments on Thursday afternoon. #Problem #UKMT #Maths

#MathsToday I vaguely remember something about AQA doing shadow papers for Core Maths. Did I dream it? If it's true can someone point me in their direction. Thanks

YES! The Maths Hubs Level 3 Leadership Communities, which I invented, are launched this month. Each Hub will have an introductory meeting, ahead of half-termly twilights for HODs and KS5 coordinators, in conjunction with the AMSP. So Network Meetings are back, baby! www.ncetm.org.uk/maths-hubs-p...

In #MathsToday we are coming back to simultaneous equations after a half term break. Before half term we were solving equations by changing one coefficient. I gave the pupils my lines of working and had them annotate what is going on in each line. We then went on to do similar, but change BOTH coeff

Interwoven Maths has had an exciting Half Term, including the following: 1) interwovenmaths.com/resources A whole new homepage, allowing you to sort by popularity and search for any topic.

If you were starting from scratch with a Key Stage 3 intervention programme for children who weren’t ’secondary ready’ (for a want of a more suitable quick description) in maths, what would it be? Imagine money and resource no object.

An equilateral triangle inside a regular hexagon. What’s the angle? #geometrypuzzle

Have you checked out Desmos Notebook yet? Importing your favorite Desmos graphs into Notebook is a great way to get started. What question should we answer next? #mathsky #iteachmath #iteachphysics

Looking through some alternative sources of questions that can be used for either Y12 and/or Y13, these source of questions came as a hidden gem. Below is from June 2024 Edexcel IGCSE Further Pure Definitely worth looking at - I've used a few for my Y12s! #ALevelMaths @andrewmaths1.bsky.social

Not long now! Further Maths Core Pure Part 2 is incoming! #ALevelFurtherMaths #sneakpeak #ALevelMaths

In #mathstoday (but actually yesterday) we looked at the basics of enlargement and similar shapes. #ukmathsteachers

Introducing Desmos Notebook (beta), our newest tool that combines text, expressions, sliders, and graphs all in one place. As you get to know Notebook, we’d love to hear your feedback, feature requests, and any bugs you find. We can’t wait to see what you create! #iteachmath #mathsky #iteachphysics

In #MathsToday given that the purple and green areas are equal, calculate the gradient of the line.

A quick task on equations of parallel lines. Feel like I’m missing some of examples. #mathstoday #ukmathsteachers

Teachers! We're running a day of year 12 maths workshops on 25th June on campus in Sheffield city centre. Bring a group? They'll see the university campus and enjoy taking part in maths workshops run by university lecturers. shuoutreach.com/event/explor... #MathsToday #AlevelMathematics
