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.
