Recently, I've realized what my favorite sport to engage in is. It's a game that I learned of during my time student teaching. It's called two square. It's a fun game, but I like it more for its versatile and efficient nature. Two square is like tennis with a larger ball and no racquet or net. I'll describe the game in detail.
Ok. In two square, you have a square is drawn on concrete (such as on a playground) and it is cut in half by a line drawn through the middle of it. How big you want the square to be is at your own discretion. One half is chosen to be labeled as "A." The other is labeled as "B." The participant in A starts out by serving a rubber ball to the participant in B. The ball is about the size of a standard dodge ball. When the ball is served, it must bounce once on the ground before it leaves A and once in B. When the participant in B returns the serve, the ball must bounce once on the ground before leaving B and once in A and so on. If the ball bounces once in A, but twice in B, the student in B loses. If the ball bounces once in B, but twice in A, the student from B takes the part of the square labeled as A, and the student from A moves to B. A student also loses if on returning the ball it bounces once in their own square, but then bounces outside of the square. Those are the default rules. The participant in area A of the square can change them as they please (i.e. hitting the ball over or underhand, length of time you're allowed to hold the ball, number of hands hitting the ball, number of times the ball is allowed to bounce)
Alright. This game is versatile in a couple ways. This game can be set up anywhere. All you need is chalk, a rubber ball, and a concrete open space. This game can be played with anyone of nearly any age because even a first or 2nd grader can whoop an adult. Trust me. I've been one of those whooped adults quite frequently.
As for how this game is efficient, as I indicated in the previous paragraph, the amount of equipment you need is minimal. As is the cost. You can get a 52 count carton of chalk for $9 and a ball for $7. A basketball on its own will be at least $20. For baseball, a bat alone will cost at least around $30. Being the cheap punk that I am right now, I appreciate the opportunity costs.
