A classroom activity/game where a student reads a clue describing a geometric vocabulary word. The student who has the term they describe must stand, read the word, and give a clue for another student.
(card 1) Who has a triangle with all equal sides?
(card 2) I have an equilateral triangle.
Who has part of a line with two endpoints?
