Ask a seven-year-old how to make 2 and you will probably hear 1 + 1. Asking for a subtraction instead surprises them, and the surprise is useful. This 2nd grade differences within 10 worksheet lists eight target numbers: 2, 3, 0, 8, 7, 4, 6 and 9. Next to each one, four choices of subtraction within 10 wait beside a box. Your child works out each subtraction and ticks every one that lands on the target. Most rows have two right answers and some have three, so your child has to test them all. On the solution page, the first row is worked out with circles crossed out. A second page gives the answer key.
