My students love memory games. This memory game provides practice with lines, line segments, intersecting, parallel, and intersecting lines, rays, vertices, degree, and right, acute, and obtuse angles. There are 24 cards, (12 pairs). The directions are easy, (and are included of course), and the game is fun. This set of memory cards matches vocabulary words with the correct definitions. Also, be sure and look for my model representation, (drawings), memory game for the same vocabulary that is used with this game. It is called Lines/Angles Memory Game 1.
