Make Ten Worksheets for 1st Grade

Free printable · with answer key

Grade 1 · 40 problems · partners that make 10, including 0 and 10; make ten to add within 20 · includes answer key · CCSS.1.OA.C.6

The partner that makes 10 is what lets a sum cross 10 without a long count. Partners that make 10 asks for the partner of every number from 0 through 10, including 0 + ____ = 10 and 10 + ____ = 10. Make a ten, then add uses that partner inside a real sum. Look at 7 + 8. 7 needs 3 more to make 10, and 5 is still left from 8. The sum is 15. A child who writes 4 in the first blank is making 11, not 10. Have them show the partner on their fingers and say it before they fill the second blank. If they rush, the rest and the sum will not match.
