For this project, I printed out some silhouettes of animals found in Australia. The 5th/6th graders did these projects on a paper bag. Once the students picked out their animal, they drew it onto the paper bag sheet, remembering to fill the page as best they could, and used a Sharpie to outline it, and then drew lines to make sections to fill up the rest of the space. They had fun crumpling the sheet up into a tight ball, and trying to smooth it out. This gave it an aged, bark-like appearance. Tearing the edges gave it an aged look, too.
Next, they used earth-toned chalk pastels to fill in the sections and the animal. Once that was completed, they dipped the end of their paintbrushes into acrylic paints and made dots in circles and lines to represent Aboriginal dot painting.
I really liked how these turned out, and I think all the students enjoyed the process.
