Hi! My son is interested in playing basketball, but I don't know too much about it. Do you know anything about basketball?
Very little honestly. Although my husband played in college and both my boys have played in high school. We are really more of a baseball family. I like that it's one of the limited-contact sports. No football for us! 
My son played baseball for many years, so we're more of a baseball family too! How many players are on a basketball team?
On a basketball team, it's 5 on the court at any given time. But sometimes they play variations, like three-on-three.
