It is important for children to be able to explore rocks outside. I also think it is important for children to be able to explore rocks inside the classroom. In fact as a teacher of small children, I know there is much to be gained by offering children a chance to play with rocks on a regular basis all around the classroom and especially at the sensory table. To that end, below is an example of how I set up rocks on a table for the children to use in the sand table.

If rocks are important for some fundamental operations that emerge from our DNA, shouldn't there be a place in the classroom for them? What do you think?
