Early start this morning for my trip to London to take part in the @mathshorizons.bsky.social session looking at their new problem solving framework.
Looking forward to catching up with many of my friends and colleagues in maths education and getting into a fascinating area of debate.

Came across something today - not sure if it is interesting or not? Fellow #maths teachers might have a view.
Take each of the fractions 1/2, 2/3, 3/4, 4/5, 5/6, 6/7, 7/8, 8/9, 9/10, and 10/11 (the first 10 fractions of the form x/(x+1)).
Add 1/6 to each of them. You might notice something.

I am starting a series on teaching "hard-to-teach" topics in GCSE maths.
The first of these articles looks at vector proof, and how teachers of maths might approach teaching vector proof so that it makes sense for more pupils.

Finally home after two long but productive days supporting the development of maths in the @stoccat.bsky.social secondary schools. Viewed some lessons, planned and delivered some INSET, and even managed to do a bit of teaching!
Looking forward to being back there in January.

It took 7 hours and 20 minutes to travel from Nanu Oya to Colombo at an average speed of 28 kmph. How long is the railway?
Try it without a calculator for a challenge :)
