This is one of those amazing sheets which keep them going for quite a while! I’ve tried this with a lower set Yr10, an extension class in Yr8 and even a few teachers! It’s hugely differentiated all on one sheet and the way it’s laid out encourages students to wander to another shape if they get stuck – some of these are really hard.
I quite often offer scissors but most people quickly realise that they prefer just to do it with a pencil and visualising it – which of course is the whole point!
