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
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).
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

/ Directions: Determine which equation is true or false. Explain your thinking.
1. Circle the equation that is true. Explain how you know it is true.
5 + 8 = 13 - 3
3 + 5 = 11 - 2
14 - 5 = 10 - 1
Explanation:
2. Circle the equation that is false. Explain how you know it is false.
12 - 7 = 14 - 9
8-4=2+3
15 - 8 = 3 + 4
Explanation:
MP2: What steps helped you solve your problems? MP4: How do you know your answers are correct? MP8: What strategies did you use to help solve your problems?
