Uses of Geoboards

Note that Geoboards can be used for most lessons involving polygons, straight lines, and integer coordinates. However, a Geoboard can only represent line segments, and thus, a lesson involving points, such as plotting coordinates in the first quadrant, can't be done using a Geoboard.
