About This Board

A high-school geometry review covering angles, triangles, polygons, circles, area, volume, and coordinate geometry. This is a Grades 9–11 Math review game in a Jeopardy-style format: a teacher puts the board on one screen, teams pick clues by point value, and the class answers out loud — no student devices or accounts needed. Categories: Angles, Triangles, Polygons, Circles, Area & Volume.
