5-Step Plan for Division Problems

Area Division

Area Division is an alternative to long division.  I have been teaching elementary and middle school children for over a quarter of a century.  Long division confuses more children than almost any other educational concept.  In order to be successful at long division, children need to not only know their multiplication facts, but they must also write in neat columns.  Beyond that, children need to be able to make educated guesses as to how many times the divisor will fit into the dividend.  When they guess wrong, they have to erase and start over.  The entire process is confusing and quite frustrating for young minds.  In these videos you will see how Area  Division helps the student with these problems.

Designed so that
ANYONE can succeed at Long Division!

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 long division, I set out to develop an easier method.  I created Area Division, which is close enough to long division, that children can switch back once they understand the concepts.

Let me be clear, Area Division is NOT for children who already understand long division.  The process does take a bit more time.  However, Area Division is structure in such a way that absolutely anyone can successfully divide large numbers.  I developed Area Division by incorporating skip counting, (I refer to it as “counting by the numbers” in my videos), and an area box for the division.  By incorporating counting by the numbers, even students who do not know their multiplication facts can successfully divide 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 fact can succeed!  For example, with the problem 535 ÷ 7; Children can write “counting by the numbers” for 7’s.  The mathematical model below 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.

7-Steps to Understanding Area Division

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 7-steps that take children for the basics of division to dividing decimals by decimals.  Because Area Division is slightly different from the conventional Long Division, 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 Division.  If not – You may want to spend a bit more time on this step.

I introduce each step of Area Division 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.

2.1- Watch Me

Unicorns to the Rescue

You are traveling through a fantastic world of dwarves, giants, and trolls.  You are high on a bluff that overlooks a great lake when 4,389 trolls attack.  There is a thunderous sound of splashing hooves.  You look across the lake to see 7-Unicorns rushing to your rescue.

How many trolls does each unicorn have to defeat in order for you to escape?

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.

 

2.2 – Work with Me

Lost Polar Bears

You are traveling through Alaska.  There are 6,391 polar bears that are lost in the tundra.  You decide to help them find their way by leading them to the nearest glacier.  However, you can only lead 8 polar bears per trip.

How many trips must you lead before all of the lost polar bears find a new home?

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.

2.3 – On Your Own

Eyes in a Peacock Muster

You own a Peacock farm.  Your favorite thing to do each morning is to look across the farm and see the muster of peacocks.  Muster is the noun we use to describe a group of peacocks.  As you know, Peacocks have the image of eyes on their tail feathers.  If a predator wants to eat them the peacocks will flash their tail feathers, and the predator will think that there are a lot of animals looking at him, so he will get scared and run away.

With their tail feathers flashing the eyes, you see 4,568 eyes.  If each tail feather has 3 eyes on it, how many tail feathers do your birds have?

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.

  1. I think that Area Division is Awesome!
    I love area division way better than long division, because it is a lot easier to understand.
    I even showed it to my big brother, and he loves it too.

  2. Hello
    This 2nd book is even easier, because I learned started on the first book. The first book helped me a lot and this second book makes doing these harder problems EASY!
