I know I'm not the first art teacher to post about these, but if you are a Target fan, like I am, these flash cards are an amazing $1 per pack! They have an animal illustration on front, with the name clearly spelled, and on the back is some information about the animal. I use them in so many ways in the art room, with all grade levels. I often deal them out like cards, and have the students practice their drawing. The information on the back is really helpful for my older students. I have them read it, and then use the information in the creation of environmental details. I find that animals are a popular topic in the art room. They are easily researched, students have a natural interest in them and they can be used in a variety of ways.
