What is a Fraction?

A fraction represents parts of a whole. It has two numbers separated by a line:

Numerator (top number): Shows how many parts we have.
Denominator (bottom number): Shows how many equal parts the whole is divided into.

For example, in the fraction 3/4:
- The denominator 4 means the whole is divided into 4 equal parts
- The numerator 3 means we have 3 of those parts

1 Whole
1/2
1/3

Fractions Less Than One

A fraction less than one is called a proper fraction. This happens when the numerator is smaller than the denominator.

Examples of fractions less than one:
• 1/2 (one half)
• 3/4 (three quarters)
• 2/5 (two fifths)
• 7/8 (seven eighths)

These fractions are all less than one because the numerator (top number) is smaller than the denominator (bottom number). They represent parts of a whole, not a whole or more than a whole.

Proper Fraction Rule

Numerator < Denominator

If the numerator is less than the denominator, the fraction is less than one.

Visual Fraction Models

We can represent fractions less than one using different visual models:

1. Area Models: Shapes divided into equal parts
- Circle models (pies divided into slices)
- Rectangle models (bars divided into sections)

2. Set Models: Groups of objects where some are selected
- 3 out of 4 balloons are red
- 2 out of 5 stars are highlighted

3. Length Models: Number lines where we mark points between 0 and 1

All these models help us understand that a fraction represents part of a whole.

1/2 as a circle
3/4 as a bar
3/4 as a set

Fractions on a Number Line

We can represent fractions less than one on a number line between 0 and 1.

Here's how to place fractions on a number line:
1. Draw a line and mark 0 on the left end and 1 on the right end.
2. Divide the space between 0 and 1 into equal parts based on the denominator.
3. Count the number of parts from 0 based on the numerator.

For example, to place 3/4 on a number line:
- Divide the space between 0 and 1 into 4 equal parts
- Count 3 parts from 0
- Mark the point at the end of the third part

¼
½
¾

Comparing Fractions Less Than One

We can compare fractions less than one to see which is larger or smaller.

Same denominator: Compare numerators
Example: 3/5 > 2/5 (same-sized parts, more parts is larger)

Same numerator: Compare denominators
Example: 1/3 > 1/4 (same number of parts, but larger parts when whole is divided into fewer pieces)

Different numerators and denominators: Find a common denominator or use visual models
Example: Compare 2/3 and 3/4
- Common denominator: 8/12 and 9/12, so 3/4 > 2/3
- Visual models: Draw both fractions to see which is larger

1/2
1/3
1/4

1/2 > 1/3 > 1/4
