  1. 6 · 6 + 0 = 6. Adding zero never changes the number.
  2. 19 · 14 + 5 = 19. You start at 14 and count on 5 more.
  3. 12 · 12 - 0 = 12. Taking away nothing leaves the number the same.
  4. True · Adding 0 means adding nothing, so the number stays the same.
  5. 17 · 12 + 5 = 17. Count up 5 from 12.
  6. 11 · 15 - 4 = 11. Count back 4 from 15.
  7. 12 · 18 − 6 = 12. Count back 6 from 18.
  8. 15 · 7 + 8 = 15. You can make a 10 to help you.
  9. 15 · 20 - 5 = 15. Count back 5 from 20.
  10. He counted one hop too few · 14 + 5 lands on 19. Tom stopped one hop too soon.
