This digital activity introduces the Commutative Property of Addition using 2 and 3-digit addends. In the interactive Google Slides, students use movable pieces to rearrange the addends to create a new problem and discover the sums are the same! Video instructions for students are included. While completing this activity students will discover this property of addition themselves!

This resource can be used to direct your whole class lesson, or easily assigned in Google Classroom or any platform that is compatible with Google Slides.

This activity is perfect for 3rd grade students or 2nd grade students who need a challenge to keep them growing as learners.
