Our Properties: Strategies to Add and Subtract lesson plan introduces students to the commutative and associative properties as they relate to addition and subtraction of whole numbers. During this lesson, students are asked to practice identifying which property is used, as well as using the properties to solve problems. Students are also asked to complete an interactive activity in which they roll dice to decide which numbers to add and subtract, then complete each problem.
At the end of the lesson, students will be able to apply the commutative and associate property when adding two or three whole numbers.
