Lesson Worksheet: Associative Property of Multiplication Mathematics • 3rd Grade

In this worksheet, we will practice identifying and applying the associative property of multiplication to multiply three one-digit numbers with products up to 10×10.

Q1:

To draw a model to show (7×4)×2, Chloe draws an array to show 7×4 and uses the third number to tell her how many copies to make.

How can she draw a model to show 7×(4×2)?

  • A
  • B
  • C
  • D

Is there the same number of squares in each model?

  • ANo
  • BYes

Which equation do the models prove?

  • A(7×4)×2=7+(4×2)
  • B(7×4)×2=7+(4+2)
  • C(7×4)×2=7×(4×2)
  • D(7×4)×2=7×(4+2)

Q2:

Compare the expressions. Pick the symbol that is missing.

  • A>
  • B=
  • C<

Q3:

Sophia drew 5 arrays with 2 rows and 3 columns.

Use her picture to find the missing number. 5×6=5××3.

Find another expression that is equal to 5×6.

  • A10×3
  • B11×1
  • C4×8
  • D4×7

Q4:

When we multiply three numbers, we can choose which calculation to do first.

Do the highlighted calculations to find the missing numbers.

What is 6×5×2?

Q5:

Fill in the blank with the missing factor: 2×(×3)=18.

Q6:

Complete: 2×(4×8)=(×)×8.

  • A1, 2
  • B2, 8
  • C2, 4
  • D4, 8
  • E1, 4

Complete: 2×(4×8)=×8.

Q7:

Fill in the blank with the missing number: 2×3×=24.

Q8:

Jackson wants to multiply 2, 3, and 4.

He thinks of grouping them as follows: (2×3)×4.

Write another way to group these numbers which shows the associative property.

  • A(2)×(3)×4
  • B(2×3×4)
  • C(2)×3×4
  • D2×(3×4)

Find the answer.

Q9:

Solve 4×5×2.
