One player starts by reading his or her "Who has" question. All players look at their cards. The player with the correct answer responds with their "I have" answer, followed by their "Who has" question. Play continues until the sequence returns to the first player. Each game includes 36 sturdy laminated cards measuring 3.5" x 5" and an answer key. Provides practice with vocabulary, recognition of angle relationships, identifying angle relationships for parallel lines and triangles, and basic computation based on angle relationships.
