A simple art idea. Have students trace their hand, then draw straight lines going left to right. When they reach their hand, they then draw a curved line. This gives the impression of a 3D hand on the page.
Some of my first graders got the hang of this, other didn’t. I didn’t have as much time as I’d have liked to explain this idea, as I was spending most of my time working on a blotting art project with the other half of the class (idea to appear here soon!). Even though the 3D element of the hand got a little lost, they still came out with some good artwork.
