How to store LEGO in the classroom?

I often get asked what is the best way to store LEGO in a classroom environment. Jim's recent post is an excellent solution for the majority of people but may not suit a classroom, which often involves many kits and must be easy to secure / transport around various classrooms.

As part of the LEGO engineering mailing list, we asked the question "How do you store your LEGO kits?" and got a wide range of answers from teachers all over the world. I've collected all the different responses and turned it into a pdf that you can download from here - www.domabotics.com

If you are a teacher using robots in your classroom, how do you store your LEGO?

Edit: Dave Parker has another excellent method: "I use 12 gallon storage tubs with the built-in hinged lids, which are sturdy and stack well on the floor, or in a car/truck. For holding parts, these can hold two of the LEGO Education boxes (e.g. 9797 + 9648), each of which has the two sorting trays. Or for student kits and in-progress projects, they can hold one LEGO Ed box on the bottom with plenty of room on top for the robot and partially assembled stuff still protected inside the tub."
