Does that Equal? MGE1.OA.7 Ms. Brown - Math

MGSE1.OA.7 Understand the meaning of the equal sign, and determine if equations are true or false.

Equal Sign

Tells you that the things on each side are the same. Equal Sign Tells you that the things on each side are the same.

Examples 5 = 5 1 + 1 = 2 2 + 2 = 4

True or False A true equation means both sides equal. A false equation means both sides do not equal.

True Equations 2 = 2 2 + 1 = 3 3 - 3 = 1

False Equations 1 = 2 2 + 1 = 2 4 – 1 = 2

Guided Practice Are the equations TRUE or FALSE? 2 – 1 = 2 3 + 1 = 4 4 + 1 = 5 5 – 1 = 5 1 + 0 = 1 2 + 0 = 0

Independent Practice Are the equations TRUE or FALSE? 2 + 1 = 3 4 – 1 = 3 2 – 1 = 2 5 – 2 = 2 1 + 0 = 0 2 + 2 = 4
