A collection of 5 activities involving square numbers that I’ve accumulated over the years from various sources:
- a puzzle I saw on Twitter involving recognising square numbers.
- a harder puzzle using some larger square numbers and a bit of logic.
- a sequences problem that links to square numbers
- a mini investigation that could lead to some basic algebraic proof work
- a trick involving mentally calculating squares of large numbers, plus a proof of why it works
Please review if you like it or even if you don’t!

Easy to follow, clear diagrams. Thanks
Love it - perfect to stretch those at the top on what may be considered a basic topic
