The document discusses the importance of developing physical literacy in children aged 0-6 through activities that improve agility, balance, and coordination. It defines these three skills as the "ABCs" of physical literacy. Agility involves changing body position quickly in different situations and can be developed through crawling, walking, running, and games that require starting and stopping. Balance has two types - stationary and dynamic - and both take practice through activities like standing on one foot. Dynamic balance grows with agility. Coordination is controlling all body parts during activities and can be improved through dance, catching/throwing balls, and keeping balloons aloft. The key idea is that children should have opportunities to practice these skills.
