A Gallery of Visualization DEMOS for Word Problems

The following is a gallery of demos for visualizing common geometric word problems that involve a measurement. These animations can be used by instructors in a classroom setting or by students to aid in acquiring a visualization background relating to constructing algebraic equations that model a word problem. Two file formats, gif and mov are available. It is recommended that a viewer with a stop/start feature be used when incorporating the animations in a lecture format or when students view the animations on an individual basis. There are MATLAB files to accompany each demo and Java applets for selected demos.

1. The gif animations should run on most systems and the file sizes are relatively small. 

2. The mov animations require the QuickTime Player (version 5) which is a free download available by clicking here; these file are also small. (The mov files may not execute properly in old versions of QuickTime.) 

3. The collection of animations in gif and mov format can be downloaded; see the 'bulk' zipped download category at the bottom of the following table.

4. The MATLAB files that accompany each demo are available for downloading; see the 'bulk' zipped download category at the bottom of the following table.

5. The Java applets that are available for selected demos can be downloaded with each applet in a folder; see the 'bulk' zipped download category at the bottom of the following table.
