Long Division Answers – There is an Easier Way!

 

Is There an Easier Way for Children to Learn Long Division?

For years I have watched children struggle with long division.  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 my summer break, I dedicated my all my free time to developing an alternative to long division.

For many years, we teachers have know that you can use a “Generic Rectangle” to multiply numbers.  It is actually a very easy method, and one that I teach to all my 6th grade students.  Since division is the opposite of multiplication, you should be able to use the Generic Rectangle to solve any division problem.  As a matter of fact, it does work very easily for simple problems.  However, when you start working with larger numbers like 45,286 ÷ 237 or decimals like 28.8 ÷ 0.8 it gets very complicated!

That was my challenge.  How was I going to take the concept of the Generic Rectangle and come up with a new way to do long division that was easier for children to learn?  Well, after hours and hours of trial and error, I believe that I have developed an easier way for children to divide numbers.  I will demonstrate this strategy in the following series of video-posts.

Please go in order

In order to create this new method of division, I had to start with easy problems and then test my strategy on more and more difficult problems.  This was important, because I needed to establish a step-by-step process that worked for all problems.  The process needed to work for basic problems like 724 ÷ 6.  That was easy.  The hard part was creating a process that worked equally well for higher-level problems like 28.8 ÷ 0.8.

The video-posts below will start with basic problems.  It is important that you start at the first video-post and work your way up.  If you are already in 5th or 6th grade, that may seem too easy.  However, it is important that you understand the basic concept of how this new strategy works before you jump to the same problems you’re doing in class.  If you take your time and watch each consecutive video, you will understand this new method of division.  Then you will reap the rewards of success!

Here are my Eight Video-Posts that take teachers, parents, and children through the step-by-step process of learning my latest strategy entitled, AREA DIVISION.

  6. Dividing a 3-digit number by a 2-digit number with decimal representation of the remainder (ie: 533 ÷ 82) – Coming Soon
  7. Dividing a 2-digit number by a tenth-place decimal (ie: 325 ÷ 0.8) – Coming Soon
  8. Dividing a decimal by another decimal (ie: 28.8 ÷ 0.8) – Coming Soon

How to use these Video-Posts

These Video-Post are designed in a similar manner to how I teach a concept in my class.

  • First, children will be introduced to a concept with a “WATCH ME” demonstrational video.
  • Next, children continue developing their skills by working side-by-side with me. They are given a problem and work through that problem, while they watch the “WORK WITH ME” video.
  • Finally, children perfect their skills by completing problems by themselves. Then they will watch the “ON YOUR OWN” videos.  These last videos encourage the child’s independent work, and then review the problem making sure that the child gains understanding.
