Pencil Dice
Teachers are you tired of looking for dice to use in your math class? Or are the dice you do use to loud and noisy when used?
Here is a simple solution, a regular pencil can double nicely as a 6-sided die.
Since a normal wooden pencil has 6 sides, all it takes is a pen to turn it into a die of sorts. Just pen in the numbers 1-6 on each side, and roll it along the table to pick a number at random.
