Answer key · Recall addition and subtraction facts to 10
- 1.10 — Counting on 6 from 4 gives 10.
- 2.9 — Counting on 5 from 4 gives 9.
- 3.9 — Counting on 6 from 3 gives 9.
- 4.6 — Counting back 4 from 10 gives 6.
- 5.3 — Counting back 5 from 8 gives 3.
- 6.6 — Counting back 3 from 9 gives 6.
- 7.7 — 9 − 2 = 7, so 2 + 7 = 9.
- 8.2 — 5 − 3 = 2, so 3 + 2 = 5.
- 9.6 — 8 − 2 = 6, so 2 + 6 = 8.
