using pictures really makes teaching materials flexible. When its a written word, you're sort of stuck.

The benefit of printable dice is it's cheap, but a little labor intensive. The other thing is you can throw them away and you don't feel as bad as tossing a bunch of plastic/foam. However, you can tape words/pictures onto bigger dice and get the same results. Then you don't need to have a bunch of dice in the closet.
