Fact Families and Make Ten

Answer Key - Grade 1 Math Worksheet

Use the first fact to finish the second.

  1. 4 + 9 = 13. So 13 - 4 = 9

  2. 10 + 5 = 15. So 15 - 10 = 5

  3. 7 + 7 = 14. So 14 - 7 = 7

  4. 5 + 6 = 11. So 11 - 5 = 6

  5. 3 + 9 = 12. So 12 - 3 = 9

  6. 7 + 8 = 15. So 15 - 7 = 8

  7. 10 + 3 = 13. So 13 - 10 = 3

  8. 6 + 3 = 9. So 9 - 6 = 3

  9. 3 + 7 = 10. So 10 - 3 = 7

  10. 6 + 8 = 14. So 14 - 6 = 8
