After seeing this and this, we decided to try this simple class project for end of the year teacher gifts. We gave each child (three and four year olds) a shape to decorate, with the only limitation being no stickers or three-dimensional objects. We used thick watercolor paper for the shapes and then I spray mounted them to acid-free paper and framed them together. I have found group art projects for young children rather challenging, but this allowed us to have some control of the project while giving the children the opportunity to do their own work. I think the variety of media and colors made a nice collection and represents the unique personalities of the children.
