Multiplying Three Numbers Together WORKSHEET

Suitable for Grades: 3rd Grade
CCSS: 3.OA.B.5
CCSS Description: Apply properties of operations as strategies to multiply and divide.2 Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative property of multiplication.) Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive property.)

Multiplying Three Numbers Together WORKSHEET DESCRIPTION

This worksheet aims to not only give students practice of multiplying three numbers together but also to build understanding of the laws of commutability and associativity.

Section A uses arrays to show how the order of numbers in multiplications does not matter and students will represent the multiplication of three numbers using arrays.

The focus of section B is on rearranging numbers in multiplication to make calculation easier. Here pupils will not complete multiplication problems but rather consider which pairs of numbers they would multiply first and why.

These skills are put to the test in section C as pupils will now find the products of eight sets of three numbers.

Lastly, in section D, learners will use single digits to find different ways of making 24 when multiplying three numbers together.
