Ask a six-year-old for the number that is 10 more than 47, and many will start counting on their fingers: 48, 49, 50, all the way up. It works, but it is slow and easy to get wrong. This 1st grade ten more ten less worksheet invites a faster way. Each box asks one question, such as « Which number is 10 less than 43? » In the top six boxes, your child colors the right answer among three numbers. In the nine boxes below, they write it on the line. The numbers run from 1 to 100, and the questions switch between more and less. A second page gives the answer key.
