Along the top, choose **Square **or **Circle**.

### How to Use

- Use the sliders to increase or decrease the number of columns and rows (for Squares) or the number of sectors (for Circles).
- Once the shape is divided as you want it, click on the sections to color them. Make the green and blue fractions equivalent to the red fraction.
- Click on the
**Check**buttons to see if your fractions match. (Note that all fractions must use a different denominator. You will get a message that says, "Use a different denominator," if you make an equivalent fraction that does not use a different denominator.) - Equivalent Fractions will automatically be added to the table.
- To delete a row, use the
**Trash Can**icon in the table. - To erase all recordings, use the
**Reset Table**button.

- To delete a row, use the
- Use the
**New Fraction**button to generate a new red fraction. - The
**Build Your Own**option can be used to create a red fraction of your choosing.

In the panel along the right side, choose the **Build Your Own**
option.

Create a fraction whose denominator is a prime number.

- How many equivalent fractions can you create?

Is it possible to create a fraction such that no equivalent fractions could be created with this applet?

- Find at least one.
- Can you describe the fractions for which this is possible?
