I can't fault the students for not putting them away correctly. Some bins were so bad that no matter how much I taped them, they would not stay together. In short, while these were a nice frugal idea, it didn't work out well.
This brings me to my latest Donors Choose project. I wanted a set of book bins (in addition to lots of other reading materials). Here are my book bins now.
So much better! I love the color that is added to my room. They are nice and durable too. If you haven't used Donors Choose, please try it out. The benefits are incredible. My students have a lot of access to materials that I couldn't have afforded on my own.
