This is a set of cut-and-paste worksheets designed to give third graders a structured format in which to practice mental math strategies.
There are 4 sets in this pack:
✓ Addition & Subtraction
✓ Division (including fractional terms like ”half of”)
✓ Mixed Operations
Each set includes five worksheets that increase in difficulty. The problems are written in a variety of ways to promote flexible thinking.
To complete these activities, students will cut out the 12 problems at the bottom of the page. After solving each using mental strategies, they glue the problems along the path at the top of the page starting with the smallest answer up to the largest. I suggest having students write the answers to each problem in the boxes before gluing them all down.
To help students be successful, it is a good idea to practice many mental math strategies like compensation, using friendly numbers, making ten, front-end addition, skip counting, etc. These worksheets provide plenty of opportunity to practice using these strategies independently.
Includes a total of 20 worksheets with answer keys.
