This is a game that has been around for a while. I know this because I have been around for quite a while playing this game! In this product I include a description and directions for how I play this game with my students. I also include examples of mathematical thinking in the notes that focus on strategies. A recording form is included, although when your students become skilled at playing this game , they will no longer need to keep a written record of their thinking. I hope that you enjoy playing this game as much as my students and I do!
