In my class I break the 30min class into 4 parts. 1) Introductory activity  (5 min)         -this involves a game usually to get students warmed up. 2) Fitness  (10 min)         - this involves different aerobic and strength building activities. 3) Lesson focus (10 min)         - This is where skills are developed and learned 4) Game (5 min)         - This is a game played that reinforces the skills learned in the lesson focus.
