In researching Sensory Processing Disorder I came across this brilliant website human anatomy fundamentals for artists on how to draw facial expressions. It's actually a terrific resource for the kids I work with who struggle a bit with understanding people and their surroundings. There are detailed drawings of facial expressions plus notes on which facial features are used to convey these moods. Feelings are grouped on an 'emotion tree' to show variations and degrees of emotion. Such as these below. It's very similar to a section in my 12 Annoying Monsters - Self Talk for Kids with Anxiety book, where I list words for the various emotions to help kids express more accurately how they're feeling. You can buy the book here: 12 Monsters It would be pretty easy to print off the faces as cards and play a matching game to the words that describe them. Anything that helps kids understand others is a good thing. :-)
