### In This 3rd Grade Video on Using Arrays for Multiplication…

Mr. Squeak's workshop has gotten very messy from all of his recent projects. It's time for him to organize his materials so that he knows where to find it all. However, they will need help organizing everything into tidy **rows** and **columns.** In this video, we are teaching multiplication using arrays to Mr. Squeaks and Imani.

### What is an Array in Math Multiplication?

An array is a **model** that can be used to find the **product,** or total, of a multiplication problem. We use arrays to lay out multiplication problems in **rows** and **columns.** Then, we count the number of marks to find the **product.** This is how to multiply using arrays.

You may see arrays in textbooks, worksheets and websites that are illustrated with symbols or pictures. But, when drawing your own array, it's normal to use x’s, dots, or circles.

#### What Multiplication Facts can be Found by Using Arrays?

In theory, any multiplication fact can be found using arrays! However, you may be limited by the space required to draw out all the **rows** and **columns** depending on the fact. You find multiplication facts using arrays by looking at the **expression.**To start, look at the first **factor** in the **expression** and neatly draw the same number of **rows.** Then, look at the second **factor** and neatly put that number of marks on each **rows** Finally, count the total number of marks drawn to calculate the **product.** You can repeat this process of using arrays to show multiplication concepts.

#### How to Teach Multiplication Using Arrays

Using arrays to teach multiplication is simple. Pick a multiplication fact to **model** using arrays. We will use the fact two times three. To start, look at the first **factor,** two. Neatly draw two **rows.**

Then, look at the second **factor**, three, and neatly make three circles on each of the two **rows.**

Finally, count the total number of circles made to calculate the **product.** There are six circles in total. This means the multiplication fact two times three has a **product** of six. You can use this concept to solve multiplication worksheets using arrays.

### Summary of Steps: Using Arrays to Solve Multiplication Problems

Looking at the **expression,**

Begin by identifying the first

**factor.**Next, neatly draw that same number of

**rows.**Then, look at the second

**factor**and neatly put that number of marks on each**row.**Finally, count the total number of marks drawn to calculate the

**product.**
