This is a pretty simple area but it's something that we haven't talked about yet. My goal is to cover every area of your room. First, gather all your teacher books. Next, clear a spot for them. They should be kept together so if you need to use one as a reference or to make copies you only have to look in 1 spot. Once you have a space ready for your books, play with how you want them displayed. Here are some things to try:
1. Line them up according to height.
2. Line them up according to color - all red books together, then orange. Within each color, organize them by shade (dark to light) not height!
3. Organize them according to subject. Writing books group together then reading and so on.
This is a fairly easy task and it's free. I organize my books by subject/height in my classroom. At home, I like to group books (and video games) by color because I love the way it looks. I know what color most of my books are so it's not hard to find them.
