Montessori Basics 3: Ultimate Guide to Montessori Materials & Links

My favorite "Montessori Basics" post so far - I think this could be very helpful. I've done variations of it before, but this one is definitely the most comprehensive. I'm delighted to say that for every website listed here, I have either used their materials or know them personally (or both), so I'm confident in the quality of the materials and/or information that they provide. As always, let me know if any of the links are outdated.
