If I had to pick, I think the moveable alphabet has to be my favorite work in the class. It is a work that can be modified to fit so many levels, it can be extended to meet the child where they are and you can connect it to the interest of the child.

Work with the moveable alphabet consists of what is called encoding – or spelling. Encoding almost always comes before decoding (or reading), it is very important that the child have a great deal of experiences with encoding before we present any sort of reading. And, since Dr. Montessori was so brilliant, she knew if you took away the mechanics of forming the letters (handwriting), and gave then a set of letters – the moveable alphabet – a young child could easily build meaningful words.
