Derrick Woods, the gallery teaching manager at Speed Art Museum in Louisville, shows how to play the game “How Art You Feeling?” The idea is to have students express what they’re feeling through art instead of words. Students are asked to do a “full systems check” to consider how they’re feeling beyond simple words like “fine” or “okay.” Students then create art to show these feelings and share their art with a partner, who describes what they see in the artwork.

The game encourages students be thoughtful about expressing their feelings. It also helps them learn to consider their partner’s feelings. In the video, the two young women who are game partners discuss the feelings they were trying to express and find common elements in their drawings. The activity helps students develop social awareness and relationship skills.
