Here's another great lesson for subs. This was inspired by a lesson I'm doing with my younger kids but I made it into a sub lesson for my older kids. I was inspired by the lesson found on Teach Kids Art (great blog). I also used this resource from Expressive Monkey. I asked the kids to draw themselves, then, them when they were 100 years old. To deeper the meaning of this lesson students could write a story from the 100-year-old selves about their life. These are wonderful to read and share if time allows.
