This is a lesson from Lisa Marie at Art Class with LMJ. I can tell that this would be a hit with my older kids. They create both the inside and the outside of the locker. She does ths lesson with 5th and 6th grade. She's written the post in a way that you could give it right to a sub and they should be able to take it from there.
Thanks so much for sharing the idea, Lisa Marie.
By the way, I found graphics to use with lesson by doing a Google image search for "imaginary school locker." There were a lot of graphics out there that would work.
