Draw a simple shape onto a piece of wax paper with a black permanent marker. If the student can rip tissue paper, have him rip the paper into small pieces. You can do this in advance and cut the paper into small squares. Spread enough glue to cover the shape. Place the tissue paper pieces onto the shape. It doesn't matter if you go over the edges because the shape will be cut out with scissors. When the shape is completely covered with a single layer, cover the paper with glue. I used thin lines because when you press the project together, the glue will spread. Place another piece of wax paper on top of the glue. Smooth the paper. Allow the project to dry over night. Cut out the project.
Here is a picture of the butterfly that I did with one group. I also made an earth. The outlines can be changed to match the curriculum. (pyramid-Egypt, shapes-math, etc.)
