Answer Key - Grade 1 Math Worksheet - Challenge Me

Use the first fact to finish the second.

  1. 6 + 11 = 17. So 17 - 6 = 11

  2. 11 + 4 = 15. So 15 - 11 = 4

  3. 6 + 10 = 16. So 16 - 6 = 10

  4. 7 + 10 = 17. So 17 - 7 = 10

  5. 9 + 6 = 15. So 15 - 9 = 6

  6. 10 + 4 = 14. So 14 - 10 = 4

  7. 8 + 5 = 13. So 13 - 8 = 5

  8. 5 + 11 = 16. So 16 - 5 = 11

  9. 7 + 12 = 19. So 19 - 7 = 12

  10. 3 + 9 = 12. So 12 - 3 = 9
