I apologize to everyone looking for the albums that used to be here. I am making some changes to them and will repost them here very soon. Please check back! Thank you.
Other Montessori Albums out there:
Shu-Chen Jenny Yen 3-6 Albums
Montessori R&D Cost $$ These are good. I have a near full set for Upper El from them. There are no pictures or illustrations in the editions I have from them. I find them complete and clear and are well sequenced.
A Good Blog Post Montessori For Everyone has a good blog post about Montessori Albums.
