One favorite Practical Life excercise of my children is crushing eggshells using a morter and pestle, but then what do you do? How about making eggshell chalk?
Set out a tray with a toilet paper roll, a bowl of powdered ground up egg shell, flour, Tbls & tsp, mixing bowl, optional is food coloring to be added to the water. Below is the recipe, however I have found that tripling the recipe is not enough to fill the entire tp roll. I also found wax paper works better as a wrap. The easiest technique is to use on of those cylinder shaped ice cube trays that you make for adding to water bottles, make sure to press all the air out.
