These worksheets address 1st grade common core standard OA.6: "Add and subtract within 20, demonstrating fluency for addition and subtraction within 10."
These basic worksheets will help your students develop addition and subtraction fluency. There is a "Ways to make" worksheet for each of the numbers 5-10 and a "related facts" sheet for the numbers 5-10. Both types of worksheets will help your students develop an understanding of part-part-whole relationships in addition and subtraction. Cubes or other manipulatives can be used with the worksheets so students can physically show the part-part-whole relationships. The "Related Facts" worksheets will help students understand the relationship between subtraction and addition.
I hope you enjoy using these with your kids!
