This medium worksheet shifts the focus from straight sums to missing-addend reasoning. First graders complete nine fill-in-the-blank equations such as ___ + 4 = 9, 6 + ___ = 8, ___ + 7 = 10, 8 + ___ = 10, and ___ + 5 = 6, working backward from a known total. A matching section then connects expressions like 2 + 5, 6 + 3, 1 + 3, and 4 + 6 to their sums of 4, 7, 9, and 10.
Pairing missing addends with matching trains children to think about parts and wholes, the foundation of fact families and early subtraction.

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