If you teach math, you have probably used geoboards. If your geoboards are like mine, the rubber bands have gotten old and brittle. Students seem to go through three or four in a lesson. Older students tend to shoot the rubber bands at each other.
Geoboards are a great for teaching geometry. I recently taught transformations using the Geoboard app. Students were more engaged than ever. I didn’t have any rubber bands break or fly across the room. Using a projector, I was able to display my board for the students to manipulate to the other students to see.
It is a simple app with great potential.
