More interesting snowflakes

Looking for something to entertain semi-distracted minds after the break?  How about challenging your students to fold paper and cut out a seven-sided snowflake decoration? 
Of course you could differentiate the task by starting off easier with 4- or 8-sided forms, increasing the challenge with more realistic 6-sided snowflakes, and asking particular students to bust out a 5- or 7- or 9- or 10-sided model.  Keep a chart on the board with the number of folds required and see what patterns your class can uncover.
