Here are 2 word problems that involve multiplication. Below are arrays that represent the information in each problem.
What is array method in math?
An arrangement of objects, pictures, or numbers in rows and columns is called an array. Arrays are useful representations of multiplication concepts (among other ideas in mathematics).
What is an example of an array in math?

How do you teach students arrays?
Tips for Using Arrays To Teach Multiplication Concepts:
- Have students work with rotating the array to show the commutative property of multiplication (the order of the factors doesn’t change the product).
- Have students show equal groups using an array.
- Have students break up the array to show the distributive property.
