True or False Clues

Massachusetts Department of Elementary and Secondary Education 45 min(s)

In this lesson, students will work to determine if equations involving addition and subtraction are true or false (Commutative Property such as 5+2=2+5). By the end of this lesson students will know and be able to show and explain how and why 2 sides of an equation are equal. Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known.
