If there's such a word as "binderize" I am doing it! I've seen several blog posts about using binders and there's a lot great info out there about using binders for planning, student data, etc. If you want to get started, you can read
this post from Once Upon A First Grade.. I decided at the beginning of the school year to take one month at a time (so it's not so overwhelming) and put all of the items I use for that month into a binder. I started with September and have completed October. I collect the items as I use them and then put on the finishing touches at the end of the month.
I put all of our center activities, art projects, etc. into page protectors and put them into the binder.

This process has helped me weed out duplicates and items I no longer use or need. I am hoping to have a full set of organized binders by the end of the school year!
