Lesson Plan - Get It!
”To show you how well I understand fractions, I only did half my homework!” Sorry, that won't work! Better get into this lesson!
- Have you ever had to break something apart to share it with someone?
That doesn't work too well with oranges or soda bottles!
- What does it mean to have equal parts?
- Can you think of a time when equal parts are important?
Describe a situation where equal parts matter. Discuss these questions and situations with a parent or teacher.
Dividing something into equal parts creates a fraction. A fraction is part of a whole. Fractions indicate that a given whole has been broken into equal parts. The whole can be a group, such as a team, or it can be a thing, such as a pizza or cake.

Now let’s review the key points of fractions:
- A fraction is written as a part of a whole.
- The numerator, or the top number, tells you how many equal pieces are counted.
- The denominator, or the bottom number, shows the number of equal parts in the whole.
Division is a process of sharing or dividing an amount equally. Dividing creates equal groups, with the same amount in each group. Fractions are another way to represent division. When dividing a single unit, the unit is broken into equal-sized pieces, or fractions.
For example, if a whole is broken into equal pieces, the division of the whole would look like this:
Fractions are read from top to bottom.
The number on the bottom has a “th” added to it, except the fraction “one half.”
Notice how the fraction ½ is read as “one half.” Half means “one of two equal groups.”
- So, you are probably wondering why this is important to you?
Let’s look at this example:
Four friends bought a giant cookie at the mall. They want to share the cookie equally.
- How much of the cookie will each friend get?
- What would the division equation be?
One whole divided into 4 equal parts:
1 ÷ 4 =
The friends need to cut the cookie into 4 equal parts.
Each friend will get a piece that is ¼ of the whole.
- If you were with 6 friends, would you have received a bigger or smaller piece of cookie?
- What happens to the size of the fraction as the number of pieces it is divided into gets larger?
