Subtraction within 10

About This Subtraction Within 10 Worksheet

This subtraction within 10 worksheet gives Grade 1 students focused practice with basic subtraction facts — the foundation for all future math. Problems use numbers 0 through 10 and include both horizontal and vertical formats. Students practice counting back, using number lines, and connecting subtraction to the "take away" concept. Print on US Letter or A4. Answer key included.

What Students Will Learn

Students learn to subtract accurately and to see subtraction as the reverse of addition. They practice basic facts, borrowing across place values, and simple word problems that connect the operation to real situations like giving change or comparing amounts.

How Teachers Can Use This Worksheet

• Number-line warm-up: Ask students to show a few problems by hopping backward on a number line. This makes the "take away" idea visible before they work on paper.
• Partner check: Have pairs swap papers and use addition to check each subtraction answer — a built-in review of the inverse relationship.
• Small-group re-teach: Use base-ten blocks with students who struggle with borrowing; trading a ten for ten ones makes regrouping concrete.

How Parents and Homeschoolers Can Use This Worksheet

Use everyday moments to practice — count down snacks, work out "how many are left," or figure out change from a small purchase. Encourage your child to check each answer by adding back up. Keep sessions brief and celebrate the process, not just correct answers.
