This afternoon I was searching for a ready made sub lesson on an imaginary treehouse. I just could not find one. Tonight, as I was searching for something for my bulletin board blog, I found the treehouse lesson!
I've left a similar lesson with a sub before and it turned out just fine.
This is from the blog, Blue Moon Pallette.
I also sell a PowerPoint lesson for sub. If you would like the lesson plan all ready to hand over to a sub, you can visit my TeachersPayTeachers shop here: Art Sub Lessons
