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.
