This medium-level worksheet pushes first graders to think about subtraction in reverse with two activities. Part A has 9 fill-in-the-missing-number problems like '9 - ___ = 4', forcing children to figure out what was taken away rather than just compute. Part B is a matching activity where kids draw lines from subtraction equations to their correct answers.
Together, these tasks build a deeper understanding of how the parts of a subtraction sentence relate.

Subtraction within 10
Part A: Fill in the Missing Number
Write the missing number to complete each number sentence.
1. 9 - 5 = 4
2. 8 - 3 = 5
3. 10 - 4 = 6
4. 9 - 2 = 7
5. 8 - 5 = 3
6. 10 - 4 = 6
7. 7 - 6 = 1
8. 8 - 5 = 3
9. 10 - 8 = 2
Part B: Match the Equation to Its Answer
Draw a line to match each subtraction problem to its answer.
