I agree with @honeypisquared.bsky.social and @darrenmacey.bsky.social that there’s a lot to like in this book, but this image for multiplication of mixed numbers made me itch *so* much!

I’ve said it before - this programme from @ncetm.bsky.social is one of the best PD programmes I’ve been involved with (and I’ve been around for years!)
It sounds ridiculous to say that applications for 2026 will open soon

One way of thinking of a division A÷B is to find a way to change B to 1.
In the case of 21÷3, say, we get 21/3 ÷ 3/3 = 7÷1 = 7;
in the case of 3/4 ÷ 1/4 we get 3/4 * 4 ÷ 1/4 * 4 = 3÷1 = 3.
Put another way,
If 3 shares are 21, what is 1 share?
If 1/4 share is 3/4, what is 1 share?
[Useful?? Dunno!]

The follow up in my head was what is one quarter, three quarters of, and I actually love this answer and the generalisation that ensues

Maybe a better way to ask is:
One-quarter of a number is three-quarters.
What’s the number?
One-quarter of a number is three-quarters.
What’s the number?
“What is three-quarters, one-quarter of?”
My thinking to get to an answer was way more convoluted than it needed to be!

… So, with maths particularly, if there was a way to pick the most important bits, and just do those, a student may get a 4/5 whereas when doing more they get a 3 because no time to consolidate. So a half at 5 may be more valuable than full at 3.
