Answer key · Recall addition and subtraction facts to 10
- 1.8 — Counting on 3 from 5 gives 8.
- 2.7 — Counting on 5 from 2 gives 7.
- 3.9 — Counting on 5 from 4 gives 9.
- 4.2 — Counting back 2 from 4 gives 2.
- 5.3 — Counting back 4 from 7 gives 3.
- 6.2 — Counting back 5 from 7 gives 2.
- 7.5 — 10 − 5 = 5, so 5 + 5 = 10.
- 8.6 — 9 − 3 = 6, so 3 + 6 = 9.
- 9.4 — 8 − 4 = 4, so 4 + 4 = 8.
