A favorite of mine during the Fall are owls, which also seem to be popular these days. They seem kinda autumnal, cute and aren't they supposed to represent knowledge?
This owl, which I did with my K-4th graders, used some collage elements. I first copied some sheet music (a song about birds) onto two different earthy colored papers, and then collected some newspapers and scrap paper.
The kids were told to cut a heart out of the music paper and that forms the body. You fold down the point to form a beak and up the round parts to form wings. Then tear the newspaper into little bits for belly feathers.
Its amazing how much personality you get from the kids!
