I went to a garage sale the other day (I LOVE them!) and got this book called "Making Faces" by Nick Butterworth. They don't sell it at amazon.com except as a used book. The copyright is 1993.
Anyway, the book has a fold-out page in the back that has a "mirror" on it. It's one of those sheets that has reflective material on it - but good enough so you can definitely see expressions. Every two pages, they deal with a different situation. Most of them are totally silly and made-up but they deal with real emotions. And not just sad, happy, mad. It goes into "What does your disgusting medicine face look like?" Or "What face does she make when she sees your snow monster?" Or "What do you look like when you're feeling sick?" "How do you look when you're dizzy?"
And the child uses the mirror to practice and you can do it with them too! I thought it was great for helping ds identify more complex emotions and more subtle ones. And, also to give him words to use to help identify them. He does pretty well with these in general, but it has been informative to see what he does with some of these. We haven't gone through the whole book - I figure a page or two a day would be good practice. Or going over the same ones again and again too!
I hesitate to say I only paid 25 cents for this book
So, if you ever see this book - grab it! Ds likes it because it is also silly and not like we're sitting down to practice something! Those are the best kinds of lessons in my opinion!
