Hi! Moose books are organizational notebooks. You can find tons of information about them and photos on
www.teachingheart.net.
I use a folder for homework, spelling/word wall words, parent communication, and take home work. The folders kind of divide the sections naturally. I use a divider for general information. I ordered a box of dividers three years ago and still have plenty for another year or two. I get all my supplies with my teacher budget money.
Hope that helps.
Steph
