This is an idea I had last year. I always start the year with a color theory review, every year it gets more complex. My hope is by the time they leave for middle school they get aquainted with the wheel and all the terminology that goes with it. So I created some visual aids that have become a permanet part of our classroom much like the word tree. I created people, each with a personality of a term from the color wheel. First, we meet Roy G. Biv, then Primary Pete, Secondary Sally, Warm Willy (that one always gets some laughs), Cool Carly, and Neutral Ned. Each personality has a dialoge box that expains him or her self. It is great for kindergarten and we refer to it during class in all levels.
This is a class room addition this year. We started a word tree or word wall. Whenever we discuss a new key concept art work we stick it on the wall. Then in the future when I review something and I get a blank stare I ask a student to go over to our tree, find the word we are looking for and explain it to the class. That allows the definition to be explained in student terms, because sometimes my terms are not clear to them. I find it to be a great asset in art and vocabulary.
