Answer key · Recall addition and subtraction facts to 20
- 1.16 — Counting on 11 from 5 gives 16.
- 2.13 — Counting on 11 from 2 gives 13.
- 3.7 — Counting on 4 from 3 gives 7.
- 4.10 — Counting back 4 from 14 gives 10.
- 5.7 — Counting back 7 from 14 gives 7.
- 6.15 — Counting back 1 from 16 gives 15.
- 7.9 — 16 − 7 = 9, so 7 + 9 = 16.
- 8.8 — 11 − 3 = 8, so 3 + 8 = 11.
- 9.16 — 19 − 3 = 16, so 3 + 16 = 19.
