Write two multiplication sentences for an array

Lesson Intro: Write Two Multiplication Sentences for an Array

Today we will learn how to write two multiplication sentences for an array. An array is a group of objects arranged in rows and columns. Arrays help us understand multiplication by showing equal groups. From one array, we can write two multiplication sentences by switching the number of rows and columns. This shows that multiplication can be done in different ways but still gives the same product.

Example:
If an array has 3 rows and 4 columns, we can write:

• 3 × 4 = 12

• 4 × 3 = 12

By the end of this lesson, you will be able to look at an array and write two correct multiplication sentences.
