In #MathsToday my Year 7s have discovered Blooket but i'd rather they were doing some analogue work on fractions of amounts so they are being treated to a tarsia You can nab these here: www.mrchapmanmaths.com/number I have a tarsia generator on my site too www.mrchapmanmaths.com/tools/tarsia...

In #MathsToday - Pie charts! Love this as a starting point for pie charts. Why can you work out what flag they are? Because of your ability to reason with proportion. You could make your own version of this using this flags tool shaheeilyas.com/flags/

As we begin our first lessons of the year I have used this for a few years as my first lesson activity. I absolutely love it. There's something about the way it seems impossible on first sight but as you work through it gets easier and easier that I love. nrich.maths.org/problems/sha...

Ofqual haven’t helped by perpetuating the idea that contingency papers exist for specific exams - they don’t. All an exam board can do if they need to make a late change is bring forward next year’s paper (which will be already written). For modular exams (eg C3) this was quite straightforward 1/3

In #MathsToday we did some nth term revision with Y7 with a brief Blooket at the end. I'm always impressed with no. of questions students are able to get through... 1,323 in SIX minutes for a class of 30-- 44 on average. Pretty good for those times you want lots of quick repetitive practice

A #MathArt project with my #calculus class! A "Riemondrian" art project inspired by @mathzorro.bsky.social. Students used a Riemann Sum to approximate the area under their curve. Then created additional blocks of color using custom color palettes (this one is "Moon Mist"). #ITeachMath #MathsToday

A geometric Desmos graph depicting a Riemann sum with a Piet Mondrian abstract art aesthetic. A thick, vibrant coral-pink cubic function curve waves smoothly from left to right across the square frame. The graph is filled with a grid of rectangular blocks using a "Moon Mist" ice cream color palette: grape purple, banana yellow, bubblegum blue, and crisp white. The colorful blocks form vertical columns bounded by clean, dark teal lines, abstractly representing the calculus area approximation underneath the pink curve.

In accordance with ancient tradition, our next Prime Minister is announced to the nation while standing between a furry and a man with a bin on his head.

A victorious Andy Burnham MP (24,937 votes), as the result of the Makerfield by-election is announced, flanked by defeated candidates Count Binface (a bloke in a vaguely sci-fi costume with a large bin for a helmet; 95 votes) and Robert Pownall (who is in a full body fox costume, holding a sign reading "Protect British Wildlife"; 18 votes). There are some other candidates there just out of shot but that's not important right now.
