Montessori Advice

Has anyone used the North American Montessori Center? Im looking at the homeschool curriculum but it seemed like it was missing a lot of information. Theres options to get credentials from them etc. Its high priced but I really like it and I think its what my son needs.

Montessori print shop has free stuff and really affordable prontables for every subject.

For a full curriculum I only know of Schiller. They have math and language arts for k-8 I believe.

Check out Jady A. On YouTube, she has tons of good videos for litttles.
