Equal Groups Multiplication Song | Repeated Addition Using Arrays

Video: Equal Groups (Repeated Addition Using Arrays)
Grade Levels: 2nd Grade - 3rd Grade
Check out our ever-growing library of math songs at


For 2nd Grade, using repeated addition to find the number of objects in an array sets the foundation for multiplication. By representing groups of objects in rows and columns, students can visualize and conceptualize multiplication.

In 3rd Grade, students learn to represent multiplication through arrays showing equal groups, while also spiraling back to review the use of repeated addition and it's relationship with multiplication.

Q. I'd like to show my students this video but my school blocks YouTube videos. Where else can I watch this video to work around this problem?
A. You can watch this video here; ad-free and child-safe:

Q. What grade levels do this video target?
A. This video targets learning standards in 2nd and 3rd Grade. This video also targets standards in the UK from KS2 (Year 3-4).

Q. Where did you guys come from?
A. Numberock is a project that I, Mr. Hehn, began as a 5th Grade math teacher of 7 years. It came together after years of experimenting with my lessons trying to figure out the best way to help my students retain the math concepts they were learning.

Q. Does Numberock drive real results in the classroom?
A. I knew I found the secret sauce when not only were my students retaining the concepts longer, they were singing the songs outside of the classroom during recess and at home with their parents during dinnertime. The songs were so catchy, my students couldn't get the math songs out of their head!

During testing, I often found my students humming the melodies in order to jostle their memory of a rule or problem solving process. As we've all experienced, there is something about the power of music that allows us to retain information easier and for longer periods of time. Without getting into the finer details of multi-sensory learning and how it often helps the students who most need the help, the power of a catchy song is hard to deny.

Q. I love your songs. Where can I experience more of what NUMBEROCK has to offer?

Coming Soon:

1. Number Notes | Were currently working on creating exercises where students will be able to take notes artistically on printable templates featuring characters from the videos.

Research has shown that this will help to integrate their artistic side side of the student's brain with the mathematical side of their brain which helps with long-term memory retention. Our own research has shown us that teacher's who use start using these templates love them! It seems to be a natural fit as we move beyond our unique auditory learning tools into visual learning tools, that when used in concert, cater to the different types of learners that you teach everyday.

Hope to see you at!

Equal Groups: Repeated Addition Using Arrays Song is aligned with the following Common Core standards:

Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.

Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7.

For those who don’t know, an array consists of numbers and objects etc that are arranged in columns and rows.

Arrays are useful representations of concepts like multiplication. These arrays help in making the students understand these processes easily without getting confused.

It’s basic maths for kids and for examples of an array and more explanation on how it works, you can opt to learn math online for kids.

Arrays are pretty useful to teach students the different mathematical concepts and well, thanks to the internet that we now have several online platforms where we can learn and teach the little ones on how to incorporate arrays in multiplication and division.
