My first post pointed out the many differences in our students. A physical education class differs greatly from a sports class, especially with elementary students. In a sports class your students have a common interest and probably some ability in that particular sport. In a regular PE class the students do not have those things in common. Their abilities and interests usually vary greatly.
Those thoughts drive me to offer variety to the students. In my class my games , activities, and drills are normally different from day to day. Many of these are my own creation. Dodgeball is popular, but rather than playing the same 2 or 3 versions,
I have maybe 50 or more. We might play those games using ping pong balls, dodgeballs, bean bags, soft frisbees, or even exercise balls.
I believe it's important to be able to use different sizes and types of equipment. The students learn different movements and adjust their reactions accordingly. It's also important to provide different challenges. Obstacle courses are one of the best as far as challenges are concerned. Don't limit yourself or your students.
