Adjust the value of the numerator and denominator by moving the slider or using the
**+**
or
**-**
on either side of the sliders or entering the values directly in the boxes. Change the possible denominator values using the
**Narrow Range**
,
**Limited**
, and
**Wide Range**
tabs at the top.

You can also change values on the model. Click on sections to add or remove them or use or click
**+**
or
**-**
at the bottom of the model space to add or remove whole units.
**Note:**
The squares button at the bottom left of the model space shows or hides the sections. To add or remove sections, they must be shown.

Choose
**Length**
,
**Area**
,
**Region**
, or
**Set**
on the bottom right to show different representations of the fractions. Set also lets you choose the objects.

Record fractions to the table using the
**+**
button above the table. Click individual entries to bring up the model in the model space. Move entries by selecting them and clicking below in the empty table space. Delete entries using the
**-**
button above the table. Delete all entries using the
**×**
button.

Adjust the numerator and denominator at the bottom to change the fraction. What is the result? How does the result relate to the values shown for mixed number, decimal, and percent?

When the numerator is greater than the denominator, what do you notice? What does the picture look like if the numerator is greater than the denominator? What if the numerator is less than the denominator?

Using the set model, start with the fraction
^{}
. Add the fraction to the table. What is the decimal equivalent? Change the denominator to 8 and add and remove sections until the decimal is the same as it was for
^{}
. Add this result to the table. Try to find 3 more fractions equivalent to
and record these to the table. What do you notice about the values in the table? Change to the length model and look at each fraction's model. What do you notice?
