Respecting Boundaries. Boundaries Baseball helps children understand and respect boundaries. Boundaries are essential for positive relationships with peers and adults; children who act out are often asking for the security of clear boundaries and the skills needed to respect them. Boundaries Baseball utilizes a baseball diamond format as a visual reminder for not going out of bounds. As part of the action of the play, students will also have opportunities to toss a "ball" so that it stays within the boundaries of a "strike zone."
