Organizing Tips

Our school is switching to Common Core next year.  I am trying to figure out how to organize my materials.  I organized my ISAT materials in binders.  I have tried file folders too.  I think I like the binders better, although I need quite a few!  I have all my master copies in plastic pages.  I can leave them in the pages when I make copies.  I know that I won't lose the pages like I could if they were in a file folder.  My goal is to match up my ISAT materials that I already have and place them with the coordinating Common Core objective.  Another project to do over summer...
