A couple of days ago, I was looking for something in my classroom. As I pulled out a bunch of junk stuff, I noticed a stack of transparency paper. I hated to throw it away because I was sure I could think of a way to use it. Later that day, a light bulb came on in my head. I stapled a piece of the transparency paper to a worksheet. Now my students can write on the worksheet and I can wipe it off after the work is checked. Hopefully this will help lower the amount of run offs when doing centers.
