What’s summer without baseball? Lindsey, Arun, and Ladi are done with little league for the season, but the itch to play is still fresh in their minds. Maybe they can create their own baseball field—but where to start? Diamonds, squares, pentagons, right angles! What are they? With the help of the kindly Mr. Riley, the kids learn the precise angles and measurements to create their own field. (Math topic: angles)
