I wish I could say I thought of it all on my own, but I happen to be looking at one of my blogs that I follow and I saw it on another teacher's site. Of course, I want to give that person credit and now I can't find the post, but I am very grateful that the idea was presented just as I needed it. So if it was yours, Thank you. My students might not thank you, but i appreciate you.
Anyways, they did a great job and here are a few of those drawings. I did let them alter the pictures slightly so that they could put some creativity into the photos, and I did let them get rid of the backgrounds if they didn't change them. They were supposed to at least add a shadow or simple ground so that the viewers could see the reference to the ground.
