This medium worksheet builds flexibility with missing addends and quick recall. Children solve nine fill-in-the-blank equations including 7 + ___ = 9, ___ + 3 = 8, 2 + ___ = 10, ___ + 0 = 9, and ___ + 5 = 10, then move into a matching section that connects expressions like 5 + 1, 3 + 2, 7 + 3, and 4 + 4 to the sums 5, 6, 8, and 10.
The combination of equations with the unknown in different positions and a matching activity helps first graders see that addition can be approached from either direction, deepening number sense for sums within 10.

Addition Within 10
Part A: Fill in the Blank
Write the missing word or number on each line.
1. 7 + 2 = 9
2. 5 + 3 = 8
3. 2 + 8 = 10
4. 1 + 6 = 7
5. 5 + 3 = 8
6. 9 + 0 = 9
7. 1 + 3 = 4
8. 5 + 5 = 10
9. 3 + 4 = 7
Part B: Matching
