Answer key · Recall addition and subtraction facts to 20

1.
9 — Counting on 5 from 4 gives 9.
2.
13 — Counting on 6 from 7 gives 13.
3.
6 — Counting on 2 from 4 gives 6.
4.
11 — Counting back 2 from 13 gives 11.
5.
14 — Counting back 6 from 20 gives 14.
6.
8 — Counting back 3 from 11 gives 8.
7.
16 — 19 − 3 = 16, so 3 + 16 = 19.
8.
4 — 6 − 2 = 4, so 2 + 4 = 6.
9.
8 — 17 − 9 = 8, so 9 + 8 = 17.
