I ordered some REAL Montessori materials, and I am so excited! I've wanted the knobbed cylinders for a while, but they were MUCH too expensive. Thanks to Shannon I found out about an online store that had a huge sale. I got the knobbed cylinders (and lots of other things that haven't come in yet) for 50% plus another 15% off and free shipping. O was more excited about the packing popcorns and bubble wrap than anything else. However, since opening the cylinders she's shown lots of interest in them, and I think we are going to have a great time working with them. Yay!
