This product assists a student in practicing subtraction facts with differences between 0-20. The student will be presented with shuffled puzzle pieces to be solved and then glued onto the puzzle board. Each puzzle piece must be matched with the same number (difference) on the puzzle board. Once all pieces are glued down accurately, the mystery picture will reveal itself.
This is a great activity as a extension to any math lesson, can be used as an independent activity (e.g., at a math center station), or as a homework assignment.
