The nice thing about this lesson is that it uses very limited materials, requires little to no direct instruction, and has limitless creative possibilities.
Give students a 9" x 12" piece of drawing paper. If you are in a pinch copier paper will work, too. Let them use any available drawing materials like markers, crayons or colored pencils.
The assignment: Think of a type of food that you can personify. Draw this food in a group doing some sort of activity. Give it plenty of personality.
In my example, jelly beans are performing in a rock band at a big rock concert.
This drawing lesson comes from 2011, back when I worked as a substitute teacher. At that time I would be called upon to sub for art teachers with no plans left for me. This was because the districts knew I was licensed as an art teacher and could sort of wing it.
