Over-the-Line is a striking/fielding game designed from the perspective of the Games for Understanding tactical model to serve as an alternative to traditional kickball, softball, and baseball. Over-the-Line can be modified for developmental appropriateness and tasks can increase in complexity as tactical awareness is attained. This article shares the game (along with its modifications), outlines a sample lesson, and identifies game situations, tactical decisions, and elements of skill execution that comprise the game. This should enable readers to create lessons appropriate for their students. (Contains 3 figures and 1 table.)
