Here we have a nice little puzzle for older children. The Maths Ratty is holding a huge bunch of balloons with numbers on. All you have to do is work out which balloon is left when the three problems have been answered.
Children need to know a little bit about multiples, square numbers and prime numbers to do this, so it is aimed at the older primary age range. Good for a wet break time leading up to Christmas.
