If you're wondering whether your class is ready to find 1, 10 or 100 more or less than a number, then this Year 3 Find 1, 10 or 100 More or Less Prior Learning resource is a great place to start! The worksheet includes questions that are based on previous learning from Year 1, where children need to count one more or one less, and count forwards and backwards.

Use in class before your main teaching, as an intervention or send out as homework; the choice is yours!
