I found a web 2.0 tool called Aminah's World. It is based on the work of the artist, Aminah Brenda Lynn Robinson, who created art from various fabrics, buttons, shells, feathers, strings, scraps of paper, etc. The artist's web site features a place for students to create art using objects like Aminah.
The "Create Your Own Artwork" tool lets the student choose a background and the objects to use. It has buttons to make the objects larger and smaller, and buttons to rotate the objects. The students can be as creative as they want with these features.
The web site also has a teacher section where teachers have shared lesson plans that use Aminah's World to help the students learn various concepts.
I will be back soon with my creations.
