# 5th Grade Lesson: Writing Simple Expressions with Numbers & Parentheses

Page content

Lesson Objective: The lesson is aligned to the Common Core State Standards for Mathematics – 5.OA.2 – Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them.

Materials Required: Calculator

## Lesson Procedure:

Write each numerical expression for the following.

1. add 3 and 7, then multiply 5

2. 3 times larger than the sum of 1958 and 184

3. subtract 25 - 5, then divide by 2

4. add the quotient of 8 / 2 to the product of 4 x 3

Write the meaning for each of the following numerical expressions.

5. 4 x (3 + 6)

6. 39 / 3 + 4

7. (5 + 8) - (2 + 4)

8. 18 / 2 + 4 x 5

1. 5 x (3 + 7)

2. 3 x (1958 + 184)

3. (25 - 5) /2

4. 8 / 2 + 4 x 3

5. 4 times larger than the sum of 3 and 6

6. 4 added to the quotient of 39 divided by 3

7. add 5 and 8, then add 2 and 4, then subtract the two sums

8. divide 18 by 2, multiply 4 and 5, then add the quotient and the product

## Individual or Group Work:

Write each numerical expression for the following.

1. add 4 to the product of 3 times 2

2. subtract 15 from the quotient 48 divided by 3

3. add 324 and 561, then multiply by 5

4. add 5 and 6, then subtract 2

5. subtract 15 from the product of 30 times 3

Write the meaning for each of the following numerical expressions.

6. 14 x (38 + 61)

7. 24 + 3 x 8

8. (115 + 82) x 2

9. 182 / 2 + 4 x 51

10. 18 - 6 / 3

1. 4 + 3 x 2

2. 48 / 3 - 15

3. 5 x (324 = 561)

4. 5 + 6 - 2

5. 30 x 3 - 15

6. 14 times the sum of 38 and 61

7. multiply 3 times 8, then add 24

8. add 115 and 82, then multiply by 2

9. divide 182 by 2, multiply 4 by 51, then add the quotient and the product

10. divide 6 by 3 then subtract the quotient from 18
