Commutative Property of Addition

Mr. Buffington introduces the commutative property of addition and multiplication, explaining that numbers can be moved without changing the value of an expression. He provides examples and activities to help identify and apply the commutative property. The lesson emphasizes the practical use of this property in simplifying calculations, especially in mental math. Students are encouraged to practice using the commutative property to enhance their math skills.
