Additionally, if you go to their clearance items they also have some really neat stuff.

They have sets of art and integrated topic packs. I ordered one and think they are great for HS art projects. They are originally $30 marked down to $9, I think. I purchased the movement pack on a whim on my way checking out. Now that I've had a chance to really look at it I think I'll go back for a few more.
The sets consist of 8x10 cardstock each with a picture of a painting. Some are recongnizable artists, some not. On the back is some info on the artist, about the picture and discussion topics. They also offer ideas on how the student may study the picture and use it to create a piece of their own artwork.
