Use the spreadsheet to make your own to print out and laminate. Using a paper clip and pen as a pivot point on the spinners works well with kids. Visiting websites like Shodor will provide comprehensive lesson notes on using Mystery Spinners as a rich mathematical investigation. http://www.shodor.org/interactivate/textbooks/chapter/21/1070
