The Personal Shopper game uses shopping and money-handling
in order to reinforce the idea of proportional reasoning.
The gameplay involves the player being given a certain
amount of money, and a percentage of that money is to be
spent on various items.

***FEATURED TOOL

***FEATURED TOOL
Tool: Ameba
AJ Beyer, Russell Falk, Greg Lynch
http://mathforum.org/mathtools/tool/27914/
Ameba is designed to help students gain a better
understanding of ratios and proportions. Students are
asked to eat a given amount of dots in reference to the
total number of dots on the board. The total number of
dots may not always be equivalent to the denominator in
the ratio. Students will need to use proportions and the
understanding of equivalencies between two ratios to make
the highest score.

***FEATURED TOOL

John Page
http://mathforum.org/mathtools/tool/27905
An interactive applet and associated web page that provide
step-by-step animated instructions on how to measure angles
using a protractor. Specifically, the applet uses a protractor
to measure two angles that form a vertical pair, verifying
they have the same measure.

***FEATURED TOOL
