## On-screen subtraction activities for iPad or PC

Our on-screen subtraction activities for iPad or PC are ideal if your child is following a maths mastery programme. Activities include understanding and using terms such as 'subtract' and 'subtract from' and subtracting a single digit from a 2-digit number. Bar models and number lines are options for those who need support.

## Worksheets: adding and subtracting up to 20.

In the spring term children will begin to add up to 20 and subtract from numbers up to 20. They will use their knowledge of number bonds to 10 to find number bonds to 20. Four weeks are given for this work.
