# 4-Simple Steps for Dividing – Each problem has a math tutorial video!

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

For years I have watched children struggle with long division.    One major reason that is that memorizing all the multiplication facts can be difficult for some kids.    I have seen them get more and more frustrated as they rise through the grades.  Many times they have given up by the time they get to me in 6th grade.  I have looked for an easier strategy – one where all children would be successful dividing large numbers.  During a summer break, I dedicated all my free time to developing an alternative to long division.  The end product is this series of lessons with math video tutorials.

## Area DivisionDesigned 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 Lessons Teach Area Division Each and every problem is link to a math video tutorial!

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 7-lesson that take children from 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.

##### 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!

##### Challenge 1 – Watch MeUnicorns 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?

##### 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?

##### 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?

# Lesson 3 Dividing Three digits by Two (798 ÷ 84 )

ESTIMATING WHEN YOU HAVE A TWO-DIGIT DIVISOR
Typically, children are taught to round the devisor before estimating how many time the divisor will go into the dividend.  For example, with the problem 433 ÷ 74; Children are taught to round 74 down to 70.  Next, since 7 x 6 = 42, you would multiply by 6.  But as you can see below, the 6 is too high and that would put you over, so you would have to erase and try again.

ESTIMATING HIGH WITH AREA DIVISION
When children are struggling with the basic concept of division, you need to simplify the process, so they can feel successful.  This is why I teach children to estimate high.  With some problems, like 719 ÷ 83, it does add an extra step, but as you can see in the mathematical model below; there is NO erasing and it works every time.

With this strategy, children will never get frustrated, because they guess too high and have to erase!

##### Challenge 1 – Watch Me17 Sleeping Lions

You are on a safari in the heart of Africa.  You look to the side of your jeep and see 17 sleeping lions.  As they sleep they are attacked by 816 buzzing flies that land on them and try to disturb their sleep.  If the flies are equally dispersed among the 17 lions, how many flies are on each lion?

##### Challenge 2 – Work With MeTiger Streak

# Lesson 5 Dividing Five digits by Three (64,781 ÷ 874 )

ESTIMATING WHEN YOU HAVE A THREE-DIGIT DIVISOR

In today’s classroom, children must be able to read a word problem and then apply the concepts of division to their solution.  In many cases children get flummoxed because they are asked to solve for the quotient, and they simply do not understand what is being asked of them.  Here’s a great infographic by a fellow teacher that really helps, The Owl Teacher.

Once children figure out that they are being asked to divide two numbers, they are taught to round the divisor up or down before estimating how many time the divisor will go into the dividend.  For example, with the problem 43,642 ÷ 739; Children are taught to round 739 down to 700.  Next, since 739 x 6 = 4434, you would multiply by 6.  But as you can see below, the 6 is too high and that would put you over, so you would have to erase and try again.

Is long division is the only way to solve for a problem like this?
With Area Division, children will never get frustrated, because they never guess too high and have to erase!
