##### Long Division Gets Crazy Hard for kids!

When children move into division of a 3-digit number by a 2-digit number like 769 ÷ 89, things get crazy hard. Even if kids understand how to do long division, they have to estimate how many times 89 will go into 769. When the estimate is wrong, they have to erase and try again. Many times, I find children’s papers looking like this with eraser smudges. Sometimes the papers are even ripped from so much erasing. The photo shows a student who estimated 5 first. Then he tried 7, but that was too small also. Finally, he tried 8. The actual answer is 8 with a remainder of 57. This student did get the correct answer, but many do not. All the erasing can quickly make a child feel frustrated and insecure about math.

Papers like the one shown above are typical of students would are learning to divide with long division.

If a child estimates incorrectly with Area Division, they simply make another area box and continue to solve the problem. It is much more simple, and makes children feel successful rather than frustrated! The photo below shows the same step-by-step process used on the paper above. When you watch the videos below, you will see me demonstrate both estimating correctly and incorrectly. This will show your child what to do if they make a mistake.

__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!

# Area Division

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.

### 3.1- Watch Me

*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?

###### 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.

### 3.2 – Work with Me

*Tiger Streak*

You are a scientist studying the mighty tiger on the Asian Continent. You find a streak of 37 tigers? Your team of scientists add all their stirpes and find that they have 967 stripes in all. If each tiger has the same amount of stripes, then how many stripes does each tiger have?

__This is a Work with Me Video__

__This is a Work with Me Video__

- Gather the following materials:
- A blank piece of paper
- A pencil

- Play the video below.
- Pause the video when told.
- 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.

### 3.3 – On Your Own

*Lion Dentistry*

You are an animal dentist. You clean teeth on the most dangerous of felons. You have cleaned 946 lion’s teeth. If each lion had 43 teeth, then how many lions did you work your dentistry miracle on?

###### 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.
