Addition and Subtraction with Blocks | Sums – Minuends to 20

In 1st grade and again at the beginning of the 2nd grades, students are expected to add and subtract with sum and minuends to 20. To help students gain insightful understanding (and not just facts), the use of blocks to help them visualize the addition and subtraction problems is very beneficial. My Teaching Library has a 10 page pdf (download, print and use) workbook to help students gain the practice and understanding they need for this skill…

This workbook includes:

  • 5 addition worksheets each including 12 problems to solve with visual blocks plus one addition problem for students to solve without blocks. For this final problem, students are asked to draw blocks to show their understanding.
  • 5 subtraction worksheets each including 12 problems to solve with visual blocks plus one subtraction problem where students are to label the minuend and the subtrahend.
  • Answer keys
