Story Time Game
The facilitator starts a story by saying a sentence. It then goes in a circle, each person adding a sentence onto the story-after repeating each sentence that's already been added.
Ball Toss Game
This is a semi-review and wake-up exercise when covering material that requires heavy concentration. Have everyone stand up and form a resemblance of a circle. It does not have to be perfect, but they should all be facing in, looking at each other. Toss a nerf ball or bean bag to a person and have tell what they thought was the most important learning concept was. They then toss the ball to someone and that person explains what they though was the most important concept. Continue the exercise until everyone has caught the ball at least once and explained an important concept of the material just covered.
