I use a file storage box.
I have all 12 months in it and each month has at least 4 themes to go with that month. For example....
January
Winter
Winter sports
Animals that live in the Artcic
Nursery Rhymes
Each theme has it's own file folder with craft ideas, lauguage, songs, fingerplays, science, and whatever else I can find.... things get added all the time.
Each letter of the alphabet has it's own folder as well with different activtities.
Actually time to upgrade from file box to file storage cabinet!
