Here's what I do to organize my Journey's reading teacher's edition book. It's like most basal-based reading programs, so there is one book for each unit (5 stories each), and 6 units for the year.
I used a black and white scroll sticky tab to show where our vocabulary word cards are in the book.
I used a pink and white polka dot sticky tab to show where the beginning of each story is.
I used a yellow and white polka dot sticky tab to show where the spelling words and sentences for the pretest and test are.
For each day of the week, I use a certain color folder to hold that day's materials.I keep homework, tests, and other materials on the left and classwork (which tends to be the bulkiest) on the right side.
I can get a week or more ahead with copying because I have it down to a routine and I have several sets of folders that are the same color as the ones I use for the current week.
I keep a binder with all of my originals. Post-Its with the lesson number and story name help me figure out what is where.
For guided reading, I use these folder pocket charts from Really Good Stuff. Students keep their guided reading books and worksheets in a Ziploc bag inside the pocket. They can easily put the bag in their homework folder and bring it to and from school!
What do you do to keep reading materials organized?
