This game has always been a favorite with my kids. I wanted to create a fun and challenging version for the classroom. I have included color versions that may be laminated and used in a center with vis-à-vis pens as well as a black and white version that may be copied to have available for fast finishers. In addition, there are two different sized playing boards, one with larger (and fewer) squares for younger students, and one with more squares for older students.
