This is a simple trick that I do to make my life a little easier. I have an AM and PM class and to separate them I use separate colors for pretty much everything.
My morning is all red. All their tags are red, behavior folder, journals, nametags, etc. It makes it much easier when you are going to file things or trying to organize things. Another thing I do that makes it easier for me is when the am class moves up I keep the color with them. So if the am class is red and following year they are still red because that color is always associated with their name for me.
Do you use a color coding system to separate your am and pm class?
