I have been hearing about people using 3-ring binders and their own format as their plan book. I am just curious as to why you chose to go this route, what you all include in the binder (do you add more detailed papers for Daily 5, math workshop, etc.?), and how you feel about the bulkyness of it??? I typically bring my plan book home each night....ugh! I use a store made spiral bound plan book, but will be doing Daily 3 and math workshops this year, which will probably require additional sheets anyways. So I am looking for ideas and opinions!
