Geoboards are a classic math manipulative, useful for exploring polygons, angles, area, perimeter, and many other geometry concepts. They are also a unique medium for young artists to create beautiful designs.
However, if you don’t have a geoboard (or if, like me, you always seem to run out of the color rubber band that you need), Math Learning Center offers a wonderful alternative in their FREE digital geoboard. It has a simple, intuitive interface and is available online or as an app for iOS or Android.
Geoboard challenge for young thinkers: Can you create a polygon with an area equal to its perimeter?
