Look at these cute chalkboard blocks that I found to use in the classroom! They were in the dollar spot ($3) at Target.
There are so many things that you can do with them. The first thing I thought of was just to write my teacher name for my desk — the kids are always asking me how to spell it! 🙂 I made a little video showing you a few ways that you an use them. Feel free to add more ideas in the comments.
