9 multiplayer classroom games for Geometry. Every game plays on one shared screen (smartboard, laptop or Chromebook) with no student logins, and each has a free demo you can try right now.

Central and inscribed angles, tangents, arc length, sector area and equations of circles in a game-show spin.

Rigid transformations, SSS, SAS, ASA, AAS and HL, CPCTC proofs and constructions. Claim four in a row.

Distance, midpoint, slopes of parallel and perpendicular lines and classifying shapes on the coordinate plane.

Claim squares by naming undefined terms, choosing precise definitions, fixing flawed definitions with counterexamples, and finding triangle areas with ยฝab sin C. Get 4 in a row to win.

Win logic cases with conditional statements and counterexamples. The next player can shout "Objection!" to steal a case.

Claim squares by dilating points, using dilation properties, proving triangles similar and solving side-splitter, angle-bisector and right-triangle problems. Get 4 in a row to win.

Similar triangles, the Pythagorean theorem, special right triangles, SOH-CAH-TOA and the area of any triangle. Climb the tower floor by floor.

A team review game for every Geometry math standard. Teams claim tiles on a map by answering questions, and can steal each other's tiles. Play a full review or pick the standards you want. The results show % correct for each standard.

Volume and surface area of prisms, cylinders, cones, pyramids and spheres, cross sections and scaling. Load your cargo ship first.
