We  use our 9 junk boxes  in many ways.  On this day we had a contest to see which group could sort their junk in the most different ways.

    Here is a picture of the winning group who thought of 10 different ways to sort all the bolts.  In this picture they are putting them together in groups of bolts that could stand up and bolts that couldn't.  They also thought of putting them in groups by their size, color, shapes on the top, kinds of slots, and five other ways.
