Happy Birthday, Maria Montessori!

Maria is 139 years old today. :D Many people don't really know anything about her, but she brought a huge amount of change into the world. The whole idea of child-sized furniture, and environment scaled down to the size of a preschooler--she started it! The idea of manipulatives, hands-on things for math and language... started with her!

So, happy birthday, Maria Montessori!
