For those who have not looked through this entire blog- many of my projects involve corrugated cardboard. It is free, you are teaching students to "reuse" and there are so many things you can do with it. The students have to use a blade to cut it (promoting hand and finger strength)...the downside- it could be dangerous. I have only had one student cut themselves after years of making things out of cardboard, however.
I assign the first project to high school
students taking three dimensional design. They are supposed to think about the principles of art/design when they create them.
The second project is a group project for middle schoolers. First they sketch their ideas. They need to make three squares theselves (they measure, use triangles, and cut using a snap blade knife). The individual squares need to have a couple of layers and a frame. They paint them using shades and pure color (the students know that the squares will be mounted on black). This piece won a "Best in Show" at a local art display. Click on the picture to see it bigger...
