Word Problems & Multiple Graphical Representations
This is a series of applets drawn from the website mathMINDhabits [sites.google.com/site/mathmindhabits]
that is designed for teachers of mathematics who want to deepen their understanding of the mathematics they teach
and that their students are expected to learn.
For background on this collection of applets, please read the essay entitled "Hens & Rabbits, Feet & Animals; Some Thoughts on Representing Word Problems Graphically" on the mathMINDhabits website.
