Set-up two volleyball courts. I use two nets with two volleyball standards (more participation). Spread out 5-10 hula-hoops on each side of the volleyball nets.
Divide class into two teams. The goal is to have students practice their volleyball skills (forearm pass, underhand/overhand serve, and set) by attempting to have their volleyball land in the opposing teams hula-hoops to score a point. Each time a volleyball lands and/or bounces inside the hula-hoop that person has just scored one point for their team. We play several rounds for 2-3 minutes. Once a round is over bring the students back and have them add up each individuals score to determine how many points the entire team obtained. This is a good way to focus on sportsmanship and character (making sure students are not making up their points – honesty). After we have determined the final score of each team we play another round. Things to focus on is making sure students are practicing the correct volleyballs skills as mentioned above.
Students are NOT allowed to catch, throw, kick, and/or lift the volleyballs. Make sure students do not touch the net. The volleyball must go over the net not under. When it comes to blocking (I only do this with 5th grade) students can only block while moving around their side of the net. In other words students cannot stand in front (not moving) of the hula-hoops and/or stand inside them.
You can have the volleyballs bounce on the floor then inside the hula-hoops to score points. Depending on skill level to can only allow points to be obtained when the volleyball bounces directly in the hula-hoop (before it touches the floor). For younger students; such as 3rd and 4th grade I do NOT allow blocking.
