Based on the old BBC quiz (with Bob Monkhouse). There are some numbers on the board that are (large) square numbers and others that are not (these answers wipeout).
Designed for use as a starter activity or plenary.
This particular Wipeout is a good extension for KS3 students who already have secure basic knowledge of what square numbers are.
I’ve also included the slides in a “matching cards” format that can be cut out and given to students to sort into “true” or “false” on their desks (or in small groups).
