Q

Between 2-6 years old, there’s a gain in new and important motor abilities, which serve as the foundation for movement. Provide 3 reasons why gaining this movement foundation is important in early childhood.

A
  1. These movements are important for complex sport movements when they get older.
  2. Without this, they might embarrass themselves during a game/activity which will decrease their willingness to exercise again.
  3. Important to maintain an appropriate level of physical activity.
