Sunday night seems the right time to post a gallery of (I hope!) every one of Catriona's geometry puzzles.

Give it a moment to load ... there's a *lot* of them!

Particular highlight for me this issue is the article from @janehawkins.bsky.social on the importance of purposeful talk in maths πŸ—£οΈ

More Y9 trig #MathsToday: we ditched the tables in favour of drawing multipliers directly onto the triangles. This lesson went pretty well! Still just using sin and cos, and today I kept everything in one orientation as well.

"Based on our evidence and analysis, we believe that the right approach is to maintain a single GCSE in maths... Reintroducing parallel qualifications would very likely widen socio‑ economic gaps, and face the same fate as the failed pilot in England and the abandoned policy in Wales."

"In England, a 2010 pilot that split maths exams into β€œmethods” and β€œapplications” found several problems, including that teaching time became fractured, and that most schools entered students for only one paper, which led to β€œsocial sorting” and less value being put on the numeracy paper."

"In our consultations, we heard many suggestions on these issues, including that the above problems could be fixed by splitting GCSE Maths into a more-academic β€œpure” paper and a more-applied, β€œnumeracy” paper. However, evidence cautions against this."

From the @mathshorizons.bsky.social report May 2025:

"We believe that reasoning and problem solving are not separate strands of maths, to be visited in isolation: they are part of what it means to do maths. The curriculum should reflect this truth at every level."

A poem about what happens when the I-we-you structure starts to have more focus than the learning.

#MathsEdPoetry day 3 (well almost, I won't have time in the morning!)

The I-we-you structure in lessons can easily become an "I", then, "I-again-but-with-minimal-pupil-interaction", then, "Off-you-go-whether-you-understand-it-or-not" structure instead.

This is a pupil perspective.

Both the @atmmathematics.bsky.social principle "the power to learn rests with the learner" and Daniel Willingham's phrase "learning is the residue of thought" point to the idea that learning is done by the learner. It is not something that can be done to them. From MT287.
