Writing Simple Expressions with Numbers and Parentheses

written by: Donna Ventura • edited by: Carly Stockwell • updated: 5/28/2014

In this 2nd lesson plan in a series, your 5th grade class will write simple numerical expressions with numbers and parentheses.

  • slide 1 of 3

    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

  • slide 2 of 3

    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

    Answers:

    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

  • slide 3 of 3

    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

    Answers:

    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
