I have seen a few references to this here and there. I kind of get the concept--like toys where you push a button and the same thing happens involve predetermined play--no imagination, etc. And playsilks can be used for anything, so they are completely open-ended. So those are the two extremes. I'm not as clear on other things. What about play kitchens, for instance? Would those be considered open-ended, encouraging creative play? What about toy cars? This is a new concept for me and I'm very interested in learning more--I'd appreciate any input. Thanks!
