Basketball was invented by a Canadian doctor named James
Naismith, who was born in 1861. When he was a college teacher,
he was asked to think of a game that could be played in the
winter. Dr. Naismith created a game to be played inside on a hard
floor. Dr. Naismith divided the men in his class into two teams and
taught them to play his new game. Players on the same team
must work together to get the ball in the other team’s basket. At
the same time, they need to stop the competing team from getting
the ball into their own basket.
