Today I realised that “integrates like” is the phrase I’ve been missing for talking about spotting the structure of an integral. #ALevelMaths #MathsToday

I recently worked on a fun problem involved the Pokémon TCG. Here's a post about the problem and my thought process/solution. jclevelandtran.com/2025/10/15/s...

In the Pokémon TCG Pocket app, I would earn 10 points for winning a match and lose 7 points when losing a match. However, you also get a win streak bonus – the second win in a row gets a bonus of 3 points, the third gets 6, the fourth 9, and the fifth (and all subsequent) gets 12. Assuming I have a win rate of 50% (which I did at the time), what’s my expected value for playing n games? (How many games would I expect to play to earn x points?)

I just took a train on Friday and was in the quiet car and it was heaven! My trip was only 2.5 hours though.

Loved this HS student's #fractal, so #geogebra'd it up mathhombre.tumblr.com/post/7970450... #mathart

Very nice! The calculations will get a little funky since the rule is a little different for those squares that have larger squares on bothe sides.

Year 10 found expressions for shaded areas.
Made this last year for an extension but it was nice spending a bit longer on it.

Here is a @desmos.com activity about the symmetry-preserving transformations of a square, inspired by my colleague Tom Jameson.
