3-Simple Steps for Multiplying Numbers like 736 x 8!

 3-Steps Make Multiplication Simple!

Step 1 – Write your “Counting by the Numbers” for one of the factors (the numbers you are multiplying).  In this case I wrote 8’s.
Step 2 – Draw your Area Box, and break it into 2-parts.  Next write your factors as hundreds + tens + one.  Now, Use the counting by the numbers as I demonstrate in the video below to multiply these numbers.
Step 3 – Finally, add all your products (the product is the answer for multiplication)  together.

The “1.1 Watch Me” video below shows a
detailed explanation of this problem!
There an Easier Way for Children to Learn Multiplication!

For years I have watched children struggle with Multiple Digit Multiplication, which begins with problems like, 736 x 8, then quickly increases in difficulty to problems like, 574 x 763, and finally culminates in multiplying decimals like 5.83 x 7.3.  Children who are struggling with Multiple Digit Multiplication are smart kids!  However, they have some gaps in their learning when it come to multiplication.  Simply repeating the same strategies they were taught when they first started learning multiplication will not work.  So, I looked for an easier strategy – one where all children would be successful multiplying large numbers.  I decided to incorporate Counting by the Numbers, an Area Box, and Simple Addition.

Area Multiplication
Designed so that
ANYONE can Succeed at Multiplication!

Hello, my name is Brian McCoy, and I am a credentialed teacher in the state of California.  I have been teaching elementary and middle school children for over a quarter of a century.  After years of watching children struggle with the algorithm for multiplying large numbers, I set out to develop an easier method.  I created Area Multiplication.

Let me be clear, Area Multiplication is NOT for children who can already multiply large numbers like 574 x 763.  The process does take a bit more time.  However, Area Multiplication is structure in such a way that absolutely anyone can successfully multiply large numbers.

WHEN CHILDREN DO NOT KNOW THEIR MULTIPLICATION FACTS…
THEY NEED A STRATEGY!

By simply writing the “counting by the numbers” above their problem, children who do NOT know their multiplication facts can succeed!  For example, with the problem 736 x 8; Children can write “counting by the numbers” for 8’s.  The mathematical model at the top of this page shows the results.

My goal is for children is to memorize their multiplication facts.  However, until they know all their facts, they need a strategy.  Counting by the numbers is the easiest strategy to learn.  Therefore, I have added counting by the numbers to the end of each and every video.  Children who do not know all their multiplication facts should watch and count with me at the end of each of these videos until they can count by all the number on their own.  Repetition of this strategy will help in all areas of math that require multiplication.  Once a child knows all their multiplication facts, they can stop the videos after the problem is solved and before Counting by the Numbers begins.

6-Steps to Understanding Area Multiplication

I have incorporated a cyclical learning approach, where each educational concept is first introduced, then reinforced, then revisited again and again – with each subsequent step rising to the next level of competency.  There are 6-steps that take children for the basics of multiplication to multiplying decimals by decimals.  Because Area Multiplication is slightly different from the conventional multiplication, it is important that you begin the appropriate level of competency.  If you fully understand the “Watch Me”, “Work with Me”, and “On Your Own” problems, you are ready for the next step in  understanding Area Multiplication.  If not – You may want to spend a bit more time on this step.

I introduce each step of Area Multiplication in a similar manner to how I teach my students within my class.
WATCH ME

For this first problem, I encourage you to simply watch how the problem is solved.  I like to introduce any new concept in this manner, so you can relax and focus on the strategies for solving the problem.

WORK WITH ME

For this second problem, I encourage you to develop your skills by working side-by-side with me.  I would like you to watch a bit of the video, then pause it, and copy what I do on your paper.

YOUR OWN

For the remaining problems, I encourage you to solidify your skills by completing the problems on your own.  Once you have completed the problem, watch the video, and correct your mistakes.  Over the years, I have found that children make substantial jumps in understanding when they find their own mistakes and then fix them.  That is why I have included this form of teaching into this post.

1.1- Watch Me

Ernie the Photo-Hungry Emu

Ernie the Emu loves having his photo taken.  As a matter of fact, Ernie gets his photo taken more than any other animal on the African savanna.  He sticks his face in front of anyone he see with a smart phone, or a camera.  Ernie is 736 days old.  He has had his photo take exactly 8 times every day of his live.  How many photos have been taken of Ernie the Photo-Hungry Emu?

This is a “Watch Me” Challenge:

Simply watch the video below to see how this problem is solved.  Pay close attention.  Your next challenge will be very similar to this one.

1.2 – Work with Me

Moni Monarch

Moni Monarch is a hard working butterfly.  She flies from flower to flower sucking up the sweet, sweet nectar.  Once she lands on a flower, she slowly beats her wings, while she suck the nectar through her long tongue.  It takes 329 beats of her wings, before she can suck all the nectar from the flower.  If Moni Monarch gets nectar from 6 flowers, how many times must she flap her wings in order to get all the sweet nectar from these flowers?

This is a Work with Me Video
  1. Gather the following materials:
    1. A blank piece of paper
    2. A pencil
  2. Play the video below.
    1. Pause the video when told.
    2. Copy the problem down on your own paper, and solve it with me.

Pay close attention.  Your next challenge will be very similar to this one.

1.3 – On Your Own

Tommy Tortious

Tommy Tortious is on a mission.  He wants to be the first tortious to travel all the way from the Mojavi Desert to the Pacific Ocean.  He has been trekking for months.  Each day he races 4-miles across the state of California.  It will take him 673 days to get to the Pacific Ocean.  How far will Tommy Tortious have traveled by the time he reachers the coast?

Your Challenge:
Gather the following materials:
  • A blank piece of paper
  • A pencil

Solve this problem just as you did in the earlier one.

Don’t worry if you make a mistake – Some of our biggest leaps in learning come when we make a mistake then see what we did wrong and fix it.

Once you have completed this challenge, click the link below:

Keep your paper with you while you watch the video.

If you made a mistake, pause the video and fix your mistake.
That’s the fastest way to learn!

How did you do?
Were you able to complete all three problems successfully?

If you answered Yes – Then you are ready for the next level.


If you would like more time reviewing this concept, leave a comment below.  I am constantly creating new videos and ebooks.  If there is a need – I will focus on this concept.

Video-Blogs within this Series

I have planned six video-blogs for this series on Area Multiplication.  You can visit each blog by clicking on the links below.  After reviewing the post, please leave a comment.  I love hearing your thoughts.

Area Multiplication – Blog 1
Multiplying Numbers like 736 x 8
The activities within this blog will introduce you to strategies for solving problems that multiply a 3-digit number by a 1-digit number (ie: 763 ÷ 8 = 5,464).  This blog forms the building blocks of understanding for all blogs in this series.

Area Multiplication – Blog 2
Multiplying Numbers like 76 x 39
I have completed the planning stage for this series on Area Multiplication, and will post the video-blogs as I complete them.  Check back in a week or two, and I should have the next video-blog ready for you to review.
Thanks for your patience.

  1. Your method counting by the numbers is a lot easier than multiplying in your head and it helps you get your facts down quicker.

    1. Thanks Noah –
      Ultimately, you will memorize all your multiplication facts. Then multiplying these numbers will be even easier. Keep up the great work – It sounds like your improving quickly!
      Have a great day!

  2. I really like area multiplication. It makes doing multiplication a lot easier and I understand it better than the way I was taught before.
