Does the idea of having a substitute strike fear in your heart? Only with the most trusted art sub will I expect her/him to continue my on-going lessons, and then only with greatly detailed instructions left behind. For non-art subs, I tell them not try to continue my lessons, no matter how hard my students try to convince them otherwise.
This is one of my most successful substitute plans, based on a template that I leave, one per table to share. The template (drawn by me) fits on 12" x 18" white drawing paper. Students trace the pattern, draw a design in pencil first, then outline with marker, and finally color with colored pencils before cutting it out and assembling the cube. My directions ask that students come up with a detailed design that flows from one panel to another, realistic or abstract. Careful work means the activity will take more than one period, so students begin the project with the sub but finish it with me. I have used this lesson with grades 3-5 but it is certainly adaptable for higher grade levels.
If you have a favorite substitute lesson, please share it with us!
