Subtraction Worksheet 1-20

Subtraction Facts up to 20

This worksheet expands subtraction practice to numbers from 1 to 20. It bridges the gap between simple facts within 10 and larger regrouping problems that appear later in the year.

Ideal use cases

• Second grade review of subtraction within 20.
• Fluency drills before introducing multi-digit subtraction.
• Intervention work for students who still count backwards one-by-one.

Problems are carefully chosen so students can practice mental strategies like “make ten” and “counting on” rather than relying on finger counting.
