# 3 Simple Steps with Multiplication Facts for Kids that Teach How To Multiply Large Numbers

###### There’s an Easier Way for Children to Learn Multiplication!

For years, I have watched children struggle with Multiple-Digit Multiplication, which begins with problems like, 97 x 86, then quickly increases in difficulty to problems like, 5,984 x 763, and finally culminates in multiplying decimals like 5.83 x 7.3.  Memorizing all the multiplication facts can be difficult for some kids.  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.

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.  I taught this strategy to my 6th graders who struggle with multiple-digit multiplication.  After completing my series, every one of them were able to pass the educational standards for multiple-digit multiplication!

###### 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 and my 6’s.

Step 2 – Draw your Area Boxes.  In this case I need two area boxes, one for the 6 and another for the 80.  Next, Use the counting by the numbers to multiply these numbers.  (I demonstrate this strategy in a video below).

## Area Multiplicationis 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 97 x 86; Children can write “counting by the numbers” for 8’s and the 6’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 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.

##### Cyclical Learning Approach

I have incorporated a cyclical learning approach with math tutorial videos.  Each educational concept is introduced, then reinforced, then revisited again and again – with each subsequent step rising to the next level of competency.  There are 5-lessons that take children from the basics of multiplication to multiplying decimals by decimals.

##### I have scaffold these problems:
1. The first problem is a Watch ME.
Students should read the problem and then click on the video to watch how the problem is solved.
Students should copy the entire problem into their notebook.
2. The second problem is a WORK WITH ME.
Students should read the problem then gather all their materials, so that they can do the problem with me.
Students should play the math tutorial video and pause it when told.
Finally, Students should copy the problem down on their own paper, and solve it with me.
When the math tutorial video is complete, students should review the problem with their teacher or parent.
3. All the following problems are ON YOUR OWN.
Students should solve the problems just as they did in the first two.
Once you they completed the problem, they should watch the math tutorial video.
Students should keep their paper with them while they watch the video.
If they made a mistake, they should pause the math tutorial video and fix their mistake.
That’s the fastest way to learn!
