A number line helps us visualize the order of
numbers.

A number line helps us compare two or more
numbers.

We can use a number line to place fractions.
Lets look at the section between 0 and 1
enlarged.
5
To place a fraction on a number line we have to
think about the space between the whole numbers
as the whole.
6
First, look at the denominator of the fraction
and think
Into how many equal parts will the whole be
divided?
The denominator tells us how many equal parts the
whole is divided.
Divide the whole into four equal parts.
7
Next, look at the numerator of the fraction and
think
How many of the equal parts are we talking about?
The numerator tells us how many equal parts we
are talking about.
Shade one of the equal parts.
8
The point at which the shaded part ends on the
number line is the placement for the fraction.
Place a point on the number line where the shaded
part ends.
Write the fraction under the point.
9
This is what the fraction on the number line
would look like.

Lets watch a video that shows this strategy for
placing fractions on a number line.

Your turn to try.

• Follow these steps.
• Block the whole.
• Look at the denominator and divide the whole into
  equal pieces.
• Look at the numerator and shade in the number of
  pieces we are talking about.
• Place a point on the number line at the location
  where the shaded part ends.
• Label the fraction under the number line.

What if the numerator is greater than 1?Watch
the video explaining how to place a fraction with
a numerator greater than 1 on the number line.

Now lets identify fractions on the number line.

• Follow these steps.
• Block the whole.
• Determine the denominator by counting the number
  of equal pieces the whole is divide into.
• Fill in the equal parts to the point on the
  number line.
• Determine the numerator by counting the number of
  equal pieces you have filled in.
• Write the fraction under the point on the number
  line.
