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