Section 4: Reverse Gear: Subtraction and Fact Families
Subtraction is the opposite of addition! A Fact Family uses the same three numbers to create two addition equations and two subtraction equations.
Fill in the missing number to complete the Fact Family. We will use the numbers 4, 7, and 11.
| Operation | Equation |
|---|---|
| Addition | $4 + 7 = 11$ |
| Addition | $7 + 4 = 11$ |
| Subtraction | $11 - 7 = 4$ |
| Subtraction | $11 - 4 = 7$ |
Your Turn: Use the numbers 5, 13, and 8 to complete this Fact Family. (Hint: $5 + 8 = 13$)
| Operation | Equation |
|---|---|
| Addition | $5 + 8 = 13$ |
