Grades K-5 played a fun game which had four levels: Level 1: Launch your ball to the wall to hit it on the fly working on learning trajectory and timing of release, Level 2: Launch to your partner working on aim, timing and hand eye coordination Level 3: Launch your ball at a target Pin working on aim and trajectory and timing of release Different from level 1) Level 4: Team catapult which team will knock down all 9 pins first. They all had a blast, but best of all they worked on core strength by doing lots of sit-ups!
