What children practise
Subtraction asks how many are left after some are taken away. The first forest section uses answers from zero to ten. Later sections introduce larger numbers and answers up to one hundred. The fifth section mixes the earlier difficulty levels.
A child can count backwards, use objects, or think about the related addition fact to find an answer.
Try a subtraction question
Start at nine and count back four steps: eight, seven, six, five. The answer is 5.
Taking five away from seventeen leaves 12. Check by adding: 12 + 5 = 17.
