Have you ever worked with arrays? It’s a great way to visualize multiplication and these Jelly Bean Arrays are a fun way to learn.
So, today we’re grabbing our Easter candy and having some fun. Are you ready to learn?

Arrays are a great way to describe a multiplication problem and help you “see” how to get the answer.
It’s a great way to visualize multiplication. And it’s another one of those things I didn’t learn in school, but my children are. I’m glad they are!
How Do You Use Arrays In Multiplication?
First of all, let’s define an array. Quite simply, it’s a visual representative of a multiplication problem (at least in our case) using objects arranged in rows and columns.
Take the multiplication problem, 2 x 4. The first number, two, represents the number of rows. The second number, four, represents the number of columns.
So, for 2 x 4, we would create two rows with four objects each.
What Else Does the Array Show?
In the above photo, you’ve got three rows and four columns. It represents 3 x 4. Or, 4 + 4 + 4. Can you see that?
And the answer to both of those math problems is twelve.
Arrays can tell you a lot!
Jelly Bean Arrays
Now that we have an understanding of arrays, let’s grab our jelly beans and have some fun.
Our set-up was simple, I just used an index card to display my arrays and grabbed a pile of jelly beans.
Note: You can do this any time of the year. Just use M&Ms or Skittles instead of jelly beans.
The only other thing you need are some multiplication problems.
Let’s start solving!
How do you solve 3 x 2?
You’d make 3 rows with 2 jelly beans in each row. Now let’s solve. Count up the jelly beans and you’ll find 6. 3 x 2 = 6
Let’s flip the problem around? Would 2 x 3 look the same as 3 x 2?
The answer is the same, but the array would look different. To make an array for 2 x 3, you’d have 2 rows with 3 jelly beans in each row.
Keep using jelly bean arrays to work on all your multiplication problems. I love how this helps you see exactly how to solve a multiplication problem.
This is such a great math tool!
