The middle years math minds of Teulon Elementary have been working towards multiplication mastery with a game called, Multi. Built on the foundation of Tic-Tac-Toe, students can use their familiarity with this classic game as a strategic springboard to challenge themselves to select the next best move. Students grapple with important mathematical and strategic questions such as: What factors should I select to help me win? What move can I make to stop my opponent? Which products allow me to capture the most squares? With each move, students build fluency with multiplication facts, become more flexible with composing numbers through multiplication, and develop multiple representations of numbers with the support of the colourful illustrations on the game board. As the game draws near the end, the tension rises in stride with the student’s focus as they concentrate to find any way to complete their victory, or stave off defeat.
