Fundamental skill development is pivotal to understand and promote. Fundamental skills are the building blocks upon which all other skills are based off from. If you teach a child to catch a ball and everything that goes into that. Then they can use that skill is similar activities and build off from it. The same idea applies to basic motor development such as walking, jumping, an moving around in general. Teachers need to be ever aware of ways to help develop these necessary skills. They can do this by shaping the activities or environment to incorporate a wide range of different movements. A teacher must be willing to adapt activities to fit children who may be lacking in skill or just take longer to develop. The more skills they learn as a child the easier it will be for them to learn new skills when they grow up.
(http://www.aahperd.org/naspe/standards/PEPS.cfm) This is a list of position statements made by the official PE organizations. It is very clear from what they say that they want every child to have excellent opportunities to grow and have PE class. "NASPE believes that physical education is critical to educating the whole child, and that all students in grades K-12 should receive physical education on a daily basis" This statement I believe really shows how important NASPE thinks PE is and what a vital role it plays in the development of students.

It takes concentration and brain power to focus on keeping both balls going. It also teaches the muscles how to work together and expands muscle memory. These skills will be very helpful later on, especially for hand eye coordination
