What is the box method of multiplication?

Question

The box method is a way to multiply by two digit (or even larger) numbers that does not require students to regroup or "carry" numbers. It uses a couple more steps than the traditional algorithm, but can be easier for students in elementary school as they begin to learn how to multiply with multi digit numbers.

Answer 1

The box method of multiplication can be an easier way for 3rd and 4th grade students to learn multi digit multiplication without having to regroup or carry numbers. By decomposing the numbers into their tens and ones and aligning them in a box as shown in the video, students get to work with easier multiplication with multiples of 10. For example, instead of dropping down and putting a zero and then trying to multiply 4 times 23, the student works with 40 times 20 and 40 times 3. You only have to know how to multiply 4 x 2 and 4 x 3 and add zeros. Once you have multiplied all of the numbers in the boxes, you simply add everything up. This method does take a couple of steps longer to get to the answer, but it can be an alternative for students who may get confused by regrouping or carrying numbers as they multiply. This can be especially helpful for visual learners or students who become confused or distracted as they work.

Answer 2

Hello There!

I am a huge proponent of offering students a variety of methods to arrive at an answer. The traditional multiplication algorithm can be quite cumbersome for many students, particularly those with working memory challenges. There are several steps involved in multiplying larger numbers, and the box method was a lifesaver for many of my students this year. It is a way of decomposing numbers into smaller parts and organizing the process involved. Thank you for asking!
