Multiplication Arrays

My friend, Kim, at Life Over C’s has an awesome 21 day series going on her blog called “Learn with Your Craft Stash“. The series focuses on learning activities you can do with craft items you have around your home or classroom. I’m joining in today with how to use construction paper and a hole punch to teach multiplication arrays.

What is an array, anyway?  An array is an orderly arrangement (most often in rows or columns) of numbers or objects.  An array can be used as a visual representation of multiplication as repeated addition.

We use Singapore Math 1A and 1B with my youngest. Beginning multiplication is introduced in first grade right after students learn repeated addition.  Students go from learning and solving 2+2+2, to relating that to 2×3 (2 three times).

Here’s a fun and engaging activity we recently did when studying this concept.


  • Construction paper cut into small rectangles
  • hole punch
  • glue stick
  • printed worksheet with multiplication facts (optional)

First, I printed out a few multiplication facts onto a sheet of paper.  You could easily just write the multiplication facts on a piece of paper or an index card.

Next, I cut several small rectangles out of construction paper.

Then, I had my son solve the multiplication problems by making an array on the rectangle with a hole punch. We talked about how the first number told him how circles to punch. The second number told him how many columns to make of that number. So in the first example, he would make three columns of four circles (the number four, three times).

Once he punched all the holes, it was easy for him to look at the rectangle and count the holes to find the answer.  I had him work on two problems side by side with the same factors. I wanted him to see that reversing the order of the factors didn’t change the answer.  5×2 is the same as 2×5.

To make it more challenging (and to not have small circles all over your floor!), have your students create an array for the first problem.  Then, use the circles that were punched out to build another array with reversed factors.  For example, I had him create an array for 5×2 using the hole punch.  Next, he used the circles he punched to create an array for 2×5.  It was a great visual for him to see he was using the same amount of holes/circles (10), but just rearranging them in a different way.

This activity is great for both visual and kinesthetic learners.  It could also be used with addition as well.  For instance, to find the answer to the addition problem 4+3, students could punch four holes, punch three more holes, and then count the total number of holes they punched to find the answer.

My son loves using the hole punch and had a lot of fun using it to do his math problems!
