10640 : 2-Digit Addition and Subtraction Worksheets | 240 Problems to 100 | Grade 1-2 Math

This 10-page set gives Grade 1-2 students 240 addition and subtraction problems through 100, split into two columns of twelve problems each per page.

The addition column pairs a two-digit number with a one-digit number (for example 27 + 8, 65 + 7), regularly crossing a ten and requiring regrouping. The subtraction column works with round two-digit tens (50 − 20, 80 − 60), keeping the focus on place value. Twelve addition and twelve subtraction problems repeat this format across all ten pages for 240 problems in total.
