This PowerPoint has 18 slides and can be used for a whole class, small group or partner games. Basically if students answer a question correctly they use coordinate geometry to identify a square to remove on the board. As each square is removed a part of a picture is revealed. The student then can guess what they think the picture is. This is one of my students' favorite games and I use it for review for a variety of curriculum subjects. Their is an answer key below in the notes section for each slide.
