This is a great activity to use for any filler type of day. There are 2 different levels built into this power point. I put students into groups of 4-5. I then arrange 4 different desks in front of the classroom facing away from the powerpoint so the students cannot see the screen. Students take turns being the "describer" they need to describe the math vocab word. Whatever students calls out the correct math term first gets a point. There are 6 words per slide and included 40 slides. The first slide in a test slide to make sure students understand how the game is played. My students love this game!
