Candy Corn graphing

This morning I gave the kids a small baggie of  candy pumpkins and 3 different colors of candy corn:  white/orange/yellow, white/orange/brown and orange/brown.  The last column on the graph was for the "mistakes".  After placing the candy on the graph in the appropriate columns, they removed one at a time and put an X in its place.  They always have to answer my questions about their graph before they are allowed to eat their "manipulatives".
