This was a great 1 day project for 3rd graders. We started by talking about sculpture and then element of 3d. I then did a quick demo of how to fold,twist, and glue the construction paper strips to the paper. I have the students the rest of the time to work except the last 5 min. Those minuets were used for the students to take a walk around and observe the others students work.
They were pretty excited to take these works with them.
I recently found this project on another site and then forgot where I saw it, so to that teacher I am sorry I can not link this to you.
