A sketch to play with pentominoes in GeoGebra.
Many interesting math problems can be posed about these shapes, and they can be used to make fun puzzles or surprisingly challenging ones.
Got inspired to make these from a set made by David Chandler and shared at the Math Future Google group. [url]https://groups.google.com/forum/#!forum/mathfuture[/url]
A sketch with just the pentominoes, no problems, is on the tube: http://www.geogebratube.org/material/show/id/56723
If you just want the tools to make your own sketch, the .ggt file is at: [url]http://www.geogebratube.org/material/show/id/56726[/url]
