MC: 1.OA.7, 8

Today, I will determine if equations involving addition and subtraction are true or false.

Vocabulary

Notes

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

/ Directions: Determine which equation is true and which false.

1. Circle the equation that is true.

9 + 0 = 13 - 4

2+4=7-4

10 + 2 = 10 - 6

2. Circle the equation that is false.

3 + 3 = 10 - 4

7 + 1 = 11 - 3

7 + 8 = 15 - 5

Grade 1 Unit 11 Lesson 14 C SJ

Directions: Determine which equation is true or false.

1. Circle the equation that is true. 14 - 6 = 11 - 4

12- 5 = 5 + 2

1 + 5 = 16 - 8

2. Circle the equation that is false. 10 + 6 = 8 + 8

14- 5 = 5 + 4

10 + 2 = 14 - 7

*MP3: Do you agree/disagree with what

said?

*MP6: How do you know your answers are correct/reasonable?
