Subtraction Within 10 Worksheets and Activities

Within 10 is a critical skill that begins in kindergarten with counting and simple addition and subtraction, and deepens through grade 1 and 2 as students work toward fact fluency and apply these facts in word problems and equations. Resources on this page span this progression, from basic fact practice to missing addends, true/false equations, and understanding the equal sign. Concepts such as composing and decomposing numbers, part-part-whole relationships, and using strategies like counting on or making ten are reinforced through varied formats: color-by-number activities, matching exercises, word problems, and interactive games. By practicing within 10, students build automaticity that supports later work with larger numbers and more complex operations.

These resources are teacher-authored and standards-aligned, offering both printable PDFs and digital versions for flexible use. Some resources are free, while others require a Workybooks membership. The variety ensures that students at different stages of the progression can find appropriate practice, whether they are just learning to add within 10 or mastering subtraction as an unknown-addend problem.
