# Commutative

This think-pair-share task is provided for third-grade students to understand the commutative property for addition. Using a statement with single-digit numbers, students must construct an argument on whether the true statement is correct and share their ideas with a partner. A graphic organizer is provided to help students create their claim and evidence, as well as record their partner’s ideas and any similarities/differences.

Third graders are developing an understanding of the commutative property through single-digit multiplication in Same of Different?. Students are asked if two rectangles are the same given reverse length and width measurements. Argumentation language is present when asking students to explain their thinking using claim, evidence, and warrants.

# Gr 2_NBT_PropertiesCommutative_ThinkPairShare_Construct

I used this task early on for my 3rd grade class. The reason for giving this task was to allow students to see and recognize the commutative property of addition. The problem is very basic, and allows space for students to give their claim and argument, and also to have a discussion with a partner. Students struggled with understanding what the word “equals” means. They were not used to seeing an equation after the equal sign. Once students understood that equals actually means “the same,” they had a better understanding of how the commutative property works.
