Missing Addend

Worksheet Description

This worksheet is a practice tool for students learning the commutative property of addition. It features pairs of addition problems where one equation is complete and the other is partially blank, inviting the student to fill in the missing number. An example at the top demonstrates how to apply the commutative property by swapping the order of addends. The worksheet is decorated with playful frog illustrations, which adds a touch of fun to the learning activity.

The purpose of this worksheet is to teach students that in addition, the order of the numbers does not affect the sum, a principle known as the commutative property. By providing one completed equation and one equation with a missing addend, it prompts students to deduce the missing number based on this property. This activity helps students internalize the idea that numbers can be rearranged in an addition equation while maintaining the same total. Mastery of this concept builds a critical foundation for understanding more complex mathematical operations.
