Make partner puzzles for your Tubs. The puzzle showing is for the Number Family of 8. The diagram on the left illustrates how the puzzle is made. Write the number of the Family on the back of each card so lost cards can be returned to the right place.  I make 4 puzzles for each tub. Each puzzle within the tub is a different color. Place the puzzle pieces in Zip-lock bags. Students match partners to complete the puzzle.
