I have a certain system that I use, which serves me and my students well. I set up the room with spaces (or corners), designating each space a certain subject, so resources aren't scattered about the room and confusing. For example I have "my office area", "Classroom Community Space", "Math Workshop and Resource Space" and a few more. They are also marked with a cute little bunting that I made on word.
I chose to go with a black and neon theme this year, and I love it! I had some inspiration, of course, from Pinterest. Enjoy!
