What is the Rational Number Rampage App?

The Rational Number Rampage App helps strengthen math skills
dealing with fractions, decimals, and percents. This application
contains three different games:

• Rat ion al Ti mer challenges yo u to convert numbers to
fractions, decimals, or percents, and input your answer before
ti me runs out on the clock.

• Rational Match tests your memory as well as your math skills.
Sixteen cards are shown facedown. On the face of each is a
number in fraction, decimal, or percent form. For each of
these numb ers, ther e is an equival ent r epresen tation on a
different card. You turn over two cards at a time, trying to
match all of the cards using the fewest tries possible.

• Percent Square shows numbers visually on the screen using
a hundreds square (10 by 10 grid). For each problem, a
different number of squares in the grid are shaded. You must
determine what portion the grid is shaded and enter the
answer in fraction, decimal, or percent form.

For assistance in playing Rational Number Rampage, see the
tables of equivalent values for fractions less than one
