Addition using the Commutative Property: Learning “Flip-flop Facts” and Games1st Grade • Half Day Lesson Plan
Subject: Math, Operations and Algebraic Thinking
Skills: Apply properties of operations as strategies to add and subtract.2 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.)

Lesson Plan Description
First Grade half day of math lesson plans containing 2 separate segments (60 minutes each) addressing Operations and Algebraic Thinking: addition using the commutative property (OA.3). These lessons include: an introduction to the commutative property using the concept of “flip-flop” facts, whole class activity, whole class demonstration with objects, independent practice of skill, and 3 games to reinforce and practice addition using the commutative property.
- Segment 1: students will show the commutative property or “flip-flop facts” through objects and numbers, explain how the commutative property or “flip-flop facts” works, and use the words addends and sum when describing the commutative property.
- Segment 2: using the 3 games: ” Building Flip-flop Facts,” “Spinning Dominoes,” and “Roll and Flip” students will show the commutative property or “flip-flop facts” through objects and numbers.
These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
