For Grown-Ups
What this practises: addition and subtraction within 10, 20 and 100 depending on year group, including missing-number problems and simple word problems.
Suitable for: Years 1 and 2. Year 1 questions stay within 20; Year 2 introduces two-digit numbers within 100.
How to help: encourage your child to try the question first, then use "Show Me" together if they're stuck, rather than reaching for it straight away.
Try next: Number Bonds Challenge gives more focused practice with the number facts that make this quicker. Parents may also find KS1 Maths: What Parents Need to Know useful.
