Answer key · Recall addition and subtraction facts to 10
- 1.8 — Counting on 6 from 2 gives 8.
- 2.10 — Counting on 7 from 3 gives 10.
- 3.8 — Counting on 5 from 3 gives 8.
- 4.8 — Counting back 1 from 9 gives 8.
- 5.2 — Counting back 2 from 4 gives 2.
- 6.4 — Counting back 6 from 10 gives 4.
- 7.9 — 10 − 1 = 9, so 1 + 9 = 10.
- 8.6 — 8 − 2 = 6, so 2 + 6 = 8.
- 9.4 — 7 − 3 = 4, so 3 + 4 = 7.
