Description
What It Is:
A worksheet that helps students understand inverse relationships between addition and subtraction. Each problem shows an addition equation (“since…”) and asks students to use that information to fill in the missing number in the related subtraction equation (“then…”). This reinforces the fact-family connection between operations.
Why Use It:
This worksheet strengthens number sense by helping students see how addition and subtraction undo each other. It supports mastery of basic facts, encourages mental math strategies, and builds a foundation for solving more complex equations. The structured format makes relationships easy to recognize.
How to Use It:
• Review the meaning of inverse operations with students using simple fact-family examples.
• Have students read the “since” addition equation and connect it to the matching subtraction equation.
• Students fill in the missing number to complete the subtraction sentence.
• Use for whole-class practice, small-group instruction, independent work, or homework.
Grade Suitability:
Best suited for Grades 3–6.
• Students learning basic addition and subtraction facts.
• Learners developing understanding of fact families and inverse operations.
Target Users:
Elementary teachers, tutors, intervention specialists, homeschool families, and students practicing addition–subtraction relationships.
