Physical education programs should be designed to fit the needs and capabilities of children, at each different stage in their development. At the same time, they may be somewhat dependent on the facilities available. Some schools have large outdoor playing fields, lots of playground equipment, and state-of-the-art gyms; others do not. First graders will typically start out with exercises that help them explore movement. They’ll engage in basic kicking, throwing, bouncing and catching activities. Games that involve dancing and rhythm are also common. Gradually, cooperative activities are introduced, such as tug-o-war, relays, and jumping rope. In the intermediate grades, children learn about more formal games. Soccer, football, basketball and softball may begin at this time. Tumbling exercises usually continue, and kids may get to use balance beams, bars, or climb ropes. Volleyball and bowling may be taught. Finally, children will start to learn about tennis and track. Again, the activities offered will vary by school, and will depend on the budget and space available, as well as what sports are popular in a particular area.
