I'm getting ready for the national conference so I'm putting together some sub plans. Here is a quick and easy one that the kids really like. I have the sub read the book, When Sophie Gets Angry- Really, Really Angry, by Molly Bang. This is a great book for a lot of reasons. I love the texture in the images, but for this purpose, I love the emotion in it.
I printed out the image that I think was first featured on Art Projects for Kids (Thanks for finding this link Misty Hoover). It shows the steps to making an angry cat. Then students can color their cat. Finally they can flip it over and write a story about why their cat is angry. I know some subs have asked the class to share their story with the rest of the class when time allows.
