March Madness refers to a college basketball tournament. The competition takes place every March. And the madness it creates is excitement! Sometimes mad is defined as angry. But here is another definition of the word: “marked by intense and unpredictable activity.” The three-week long college basketball tournament is exactly that. It involves 64 men’s team and 64 women’s teams from colleges and universities around the country. Another reason for the madness is that people bet a lot of money on the games. In 2015, the American Gaming Association said about $9 billion is bet on the tournament. That is more than double the amount bet for the professional American football championship known as the Super Bowl. All that money is enough to drive someone crazy! The National Collegiate Athletic Association, or NCAA, puts on the basketball tournament. The competition is made up of three divisions.
