Tired of taking up a left shoe in exchange for a pencil ? Or attaching various non-pencil accessories to your pencils  so they don’t walk out on you? If you have kids unprepared for class on a regular AND you don’t like methods you’ve already tried, I have a system that worked for me.
First, a description of the environment: a majority of my students regularly entered class empty-handed.
Ingredients: gallon size zipper bags, composition books, pencils, storage crates.
My students kept their interactive notebooks in a gallon-size resealable storage bag along with a few other supplies. Because these kids have no problem walking into class empty-handed, I decided to store all they needed for class in the room. No one took anything home, or even to their lockers . Ok, so we took care of paper above. How about pencil? Keep reading, dear friends.
Each crate could hold about half of a class’ bags. I rounded up (or is it down?) and bought three crates per class, spread out all over my room. Students kept their bags in whichever of the three crates for their class. I spread the crates out to avoid traffic jams at the beginning and end of class. This worked well.
How do you make sure students are prepared for class daily?
 There seems to be a lot of precedent for the shoe-for-pencil exchange. I never liked it because, hello, puberty –> stinky feet.
 Though I do love the idea and not just because the creator is my very own roommate at #TMC13.
 That’s a lie. In practice, some more responsible students often took their materials out of class to do homework or to study. The default remained “keep your materials in class”.
