What’s an Array?

As students begin to extend their understanding of adding multiple numbers together, they may be ready to learn about representing these numbers with objects in a grid-like format. Starting in about second grade, they may be exposed to the new math term, “array.” So, what exactly is an array? Let’s break it down and make it easy for your students to understand!

In math, an array is a set of objects or symbols organized into rows and columns. Arrays are often used as visual representations to understand how equal sets can come together to equal a product.

With multiplication, arrays are used to represent the product of two numbers. For example, if you want to multiply 2 by 8, you can create a 2×8 array, which consists of two rows and eight columns, and then count the total number of items in the array, which would be 16. This helps in visualizing multiplication as repeated addition.

Multiplication With Arrays – Math Game for Kids

Teach Starter has put together a whole-class bingo game to use with your 2nd and 3rd grade students when teaching about arrays. This teacher-created resource includes 26 unique bingo boards and 24 calling cards.

To play the game, choose a calling card and read it to the students. Then, have them put a counter over the corresponding array on their game card. Remind students that the first number of a multiplication problem signifies the rows and the second number is for the columns. For example, if the multiplication fact “5 x 6” was called, this can be read as “five times six” or “five rows of six.”
