To help review place value concepts, we have been having short place value relay races. The class is divided into three groups and they sit in rows. I write three larger two-digit numbers on the board and the students compete to see who can describe the number in picture form (sticks and dots), standard notation, and expanded form. If they need help, they can ask their teammates. The team who finishes first correctly gets three points, second place gets two points, and third place gets one point.
