These are 4 of the Thumballs I have in my office. My newest ones are "Catch a Career" and "Mindfulness" from youthlight.com Youthlight offers a reduced cost the more you purchase. Thumballs can be used in small groups using the basic directions: Throw it. Catch it. Respond to the panel under your thumb. You can vary the level of difficulty by requiring one answer or three to a prompt. Kids love "props" and tools they can touch. I have used Thumballs as an icebreaker and a wrap-up activity for groups in grades 2-5. I have some larger, easier to catch balls, that require less reading for kindergarten and grade 1. My favorite is "Mindfulness" that promotes discussion about key concepts and reinforces awareness including "The Present Is a Gift."
