What a gift the simple cardboard box is! We make it a point of saving all the cardboard boxes we can put our hands on. From making impromptu trucks or carriages to sit in to houses there are many, many ways with cardboard boxes!
Cardboard lets them fly with their imagination. The children create many stories together with their props made out of cardboard and can play for long periods of time.
I love this. I need to remember to do something like this with the kids more often!
