Mathematical Concept(s) Illuminated: Illustrating fractions as decimals and percents.

How important is a demonstration prior to student use? The students will need one or two examples of how to work the applet. It will save time of confusion.

Classroom Use Comments:

• Activity setup: The students will each receive a worksheet at the computer.

• Implementation: Students will work independently at the computer station. The activity should take about five minutes (or less) each.
