Description:

This virtual manipulative enables the student to form and measure angles and triangles on an online circular geoboard. The unusual virtual geoboard offers students the opportunity to think about angles in a non-rectangular setting. This applet features five activities with discussion questions. Activities challenge students to form and use the pegs to determine the degrees of central angles and angles found in triangles. Instructions for using the applet, an outline for a lesson encouraging the use of mathematical terms, and a link to the NCTM standard for geometry are included.
