DESCRIPTION:
In this Kahn Academy video you will learn to use the commutative law of multiplication to write expressions in different ways.
OVERVIEW:
Commutative Law of Multiplication is a free educational video by Khan Academy.It helps students in grades 3 practice the following standards 3.OA.B.5.
This page not only allows students and teachers view Commutative Law of Multiplication but also find engaging Sample Questions, Apps, Pins, Worksheets, Books related to the following topics.
1. 3.OA.B.5 : Apply properties of operations as strategies to multiply and divide. 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.) (Students need not use formal terms for these properties.).
