First, there was lots of interest ... and lots of questions!
"What are these? What do we do with them?" We didn't ask our little ones to do anything in particular with the rocks, but soon they were searching for their name letters and lining them up, calling friends over, and trying out new combinations :)

They noticed that some of their names started with the same letter, and that they had to share letters to make friends' names.
Next, maybe they'll want to play a match game - we'll need more rocks!
How about numbered rocks to line up in order ... or addition rocks! We could try shapes and patterns one day, too!
Have fun!
