# 11-Steps to Understanding Fractions – This page includes math tutorial videos!

This lesson is designed to offer math help online for children who are learning fractions.  There are 2 simple strategies that I teachthroughout all 11 steps in understanding fractions.  The 1st step is to draw a box and cut it into the number of parts represented by the denominator.  The 2nd step is to color the number of parts represented by the numerator.  This is a simple, yet very effective means of developing a concrete understanding of fraction.  It is also forms the building blocks to understanding fractions how to add, subtract, multiply and divide fractions.

##### All Problems have Math Video Tutorials!
###### What happens when you add two fractions with different denominators?
• 3/4 + 2/3 = 9/12 + 8/12 = 17/12 = 1 & 5/12
###### How do you borrow when subtracting fractions?
• 3 & 1/3 – 2 & 2/3 = 2 & 4/3 – 2 & 2/3 = 1/3
###### Why do fractions get bigger when you divide and smaller when you multiply?
• 1/2 ÷ 1/4 = 2
• 1/2 x 1/4 = 1/8

# Mathematical Models Make Abstract Concepts Concrete!

By drawing Mathematical Models, your child will understand…

• That fractions are simply parts of a whole!
• Why you must have common denominators when adding or subtracting!
• Why an improper fractions is more than a whole, and how to write it as a mixed number!
• How to borrow from a whole number, to make an improper fraction, so you can subtract a smaller fraction from a bigger one!
• Why your answer is smaller when you multiply fractions, and bigger when you divide fractions!
• But Most importantly – you will gain a concrete understanding of fractions, that will help you to excel, and actually enjoy doing the math!
###### Abstract Concepts Become Concrete

When you multiply a fraction by a whole number, the product or answer is actually smaller not bigger.  Children who learn only the algorithm, do not gain a concrete understanding of why multiplication is shrinking a number rather than making it bigger.  As a matter of fact, I have spoken with many adults who have only memorized the algorithm and didn’t even realize that the answer was smaller.  In today’s classroom, memorizing the algorithm is no longer enough – children need to understand why the the math works.

###### Fractions are abstract and can be quite difficult to understand

Most people have a difficult time understanding fractions, because they never took the time to illustrate what is happening when you are working with fractions.

Mathematical Models are the most effective strategy I have ever found for developing a concrete understanding of fractions.  When you draw mathematical models, it makes the abstract concepts of math concrete, and then you can understand fractions at a deeper level.  One you understand why something works, you will begin to excel, and actually enjoy doing the math.

### 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 to ensure success.  I have broken this series on fractions into 11 steps or lesson.  You will find each lesson in the table of content below.

##### 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!

# Book 1 Illustrating Basic Fractions

##### Challenge 1 – Watch MePuppy in a Seat Belt

You and your mother bake a pan of brownies.  You cut the pan of brownies into 1/6 parts, because there will be six people at your grandmother’s birthday party.  You load the brownies into the car.  Then, you buckle your puppy next to the brownies.  You think your puppy is buckled tight, but you are wrong!  When you look back, you see that your puppy has escaped.  He is eating some of the brownies.

There is only 4/6 of the pan of brownies left.

Can you illustrate how much is left?

##### If you found this first problem helpful –  please read on! I have more problems and video after this brief message.

# Book 4 Adding Fractions with Different Denominators

Adding fractions, like 2/3 + 3/4 can be very confusing.  Unless children are taught to illustrate the addition of the fractions, they often never fully understand what is happening with the fractions.  This leaves children with a limited understanding, which can be frustrating and confusing as they enter higher levels of mathematics.
This 4th video-post continues my cyclical learning approach to the next level of understanding:

4-Steps to Adding Fractions with Unlike Denominators!

Step 1 – Illustrate the two fractions (2/3 and 3/4).  Then use your LCM (Least Common Multiple) to convert your fractions, so that they have common denominators.
Step 2 – Count up the total number of fraction parts, in this case you would get 17/12.  If you move the parts around you can change this improper fraction into the mixed number of 1 & 5/12.
Step 3 – Now move to your algorithm.  Multiply both 2/3 and 3/4 by the Giant-1, as shown above.  This will convert your fractions, so that they have common denominators.  Now you can add the numerators.
Step 4 – Make sure that your algorithm agree with your mathematical model.  In this case, you have 17/12.  If you change 17/12 into a mixed number you have 1 & 5/12, which agrees with your mathematical model.

### Mathematical Model

# Book 5 Subtracting Fractions with Different Denominators

Subtracting fractions, like 2/3 + 1/4 can be very confusing.  Unless children are taught to illustrate the subtraction of the fractions, they often never fully understand what is happening with the fractions.  This leaves children with a limited understanding, which can be frustrating and confusing as they enter higher levels of mathematics.
This 5th video-post continues my cyclical learning approach to the next level of understanding:

4-Steps to Subtracting Fractions with Unlike Denominators!

Step 1 – Illustrate the two fractions (2/3 and 1/4).  Then use your LCM (Least Common Multiple) to convert your fractions, so that they have common denominators.  If you’re new to illustrating fractions, you might want to review my first video-post in this series, An Easy Way to Understanding Fractions.
Step 2 – Once you have converted your fraction boxes according to your LCM, you’re ready to erase some of your fraction parts.  In this case you would erase 3-parts, which leaves you with an answer of 5/12.
Step 3 – Now move to your algorithm.  Multiply both 2/3 and 1/4 by the Giant-1, as shown above.  This will convert your fractions, so that they have common denominators.  Now you can subtract the numerators.
Step 4 – Make sure that your algorithm agree with your mathematical model.  In this case, you have 5/12, which agrees with your mathematical model.

# Book 8 Multiplying a Whole Number by a Fraction

Multiplying a whole number by a fraction, like 2/3 x 5 can be very confusing.
If you are multiplying, why is the answer smaller than 5?

Unless children are taught to illustrate the addition of the fractions, they often never fully understand what is happening with the fractions.  This leaves children with a limited understanding, which can be frustrating and confusing as they enter higher levels of mathematics.
This 8th video-post continues my cyclical learning approach to the next level of understanding:

3-Steps to Fully Understand Multiplying a Whole Number by a Fraction!

Step 1 – Create your fractions boxes.  In this case you would create 5 whole boxes.  Then cut each box into 3-parts.
Step 2 – count your fraction parts.  In this case you would have 10/3.  If you move the shaded parts, you can make 3-wholes and have an extra 1/3.  Therefore you answer is 10/3 or 3 & 1/3.
Step 3 – Now, move to your algorithm.  Convert your whole number into a fractions, and then multiply your numerators and denominators.  In this case you would get 10/3 or 3 & 1/3, which agrees with your mathematical model.

Is there any updates coming soon from this site?

1. Hi Selo –
I am sorry for the delay. At the end of the school year (last year), I was asked to create a series on my method of teaching division. We have a number of students at my school who struggle with long division, and I have created an alternative called area division. I created the series, but it took me all summer to complete it.
Now school is back in session, and I am teaching full time, but I will do my best to complete this series on fraction.
Thanks for reminder that I need to get back to work on fractions.

In the meantime – if you need help with division, check out Area Division
Have a great day!

Hi Brian, your “11-Steps to FULLY Understand Fractions” is so brilliant. You have a very profound knowledge on fractions. You have presented a lot of ideas on how to deal with fractions. This is very helpful to all kind of students and also to all teachers. Regarding adding and subtracting fractions, let me also share my idea on how to deal with fractions.

Adding and Subtracting fractions maybe difficult at first but keeping on practicing will make it easier in the long run. To add and subtract fractions successfully is to make the rules stick to your memory. So I have to mention again the rules here.

Rules are:
Same denominator:
Add both numerators then reduce. The result would be the final answer.
Different denominator (4 steps):
1. Multiply the numerator of first fraction to the denominator of second fraction. The result is the new numerator of first fraction.
2. Multiply the numerator of the second fraction to the denominator of first fraction. The result is the new numerator of second fraction.
3. Multiply both denominators. The result is the common denominator for two fractions.

To make it stick to your memory:
Rules for subtraction:
Same denominator:
Subtract second numerator from first then reduce. The result would be the final answer.
Different denominator (4 steps):
1. Multiply the numerator of first fraction to the denominator of second fraction. The result is the new numerator of first fraction.
2. Multiply the numerator of the second fraction to the denominator of first fraction. The result is the new numerator of second fraction.
3. Multiply both denominators. The result is the common denominator for two fractions.
4. Subtract new second numerator from first new numerator. The result is now the answer.

To make it stick to your memory:
Same numerator:
Subtract two fractions 50 times.
Different denominator:
