Today, I will determine if equations involving addition and subtraction are true or false.
Vocabulary True: any equation where the quantity on the left and the right side are equal 7=7 12 = 7 + 5 5 + 7 = 12 6+6=5+7
False: any equation where the quantity on the left and right side are not equal 10 = 7 + 2
Explanation: this equation is false because 10 does not equal 9
Copyright © Swun Math
Teacher Resources Considerations: Through this lesson students will understand the meaning of the equal sign.
Steps: 1. Determine the quantity of each side of the equal sign in each equation. 2. Find the equation that is true (or not true).
Application of MPs: MP2: What steps help you solve your problems? MP4: How do you know your answers are correct? MP8: Can you use any shortcuts to solve the problems?
