This tool enables K-6 students to build visual models of word problems. There are hundreds of built-in math problems covering thirty-six different categories. Videos explain how to model each problem type. The full screen feature makes this application compatible with interactive white boards.
"Each animation is embedded in a web page that elaborates on what you will see, but some web-browsers may not like those embeddings; for that reason I've provided direct links to each of those embedded animations on the web page in which it's supposed to appear. If clicking on a link from this page opens a page that fails to display a movie, click on the link to that movie."
