Sports fans, family, and friends have gone a little crazy the past week by calling, texting, or intently huddling around each other and filling out basketball brackets.

March is the magical time every year when 68 college basketball teams compete to win the NCAA Division I championship in men’s and women’s basketball by playing each other in a single-elimination tournament over just a few weeks.

All of the Division I conferences play their own tournaments to kick off March Madness, and the 32 winners of those tournaments get in as “automatic bids.”

The other 36 teams didn’t win their conference tournaments but impressed the NCAA selection committee enough to get offered invitations or “at-large berths.”

The names of those teams get announced in a big, televised event called “Selection Sunday.”

The 68 teams are split into four regions for the tournament.

The men’s tournament is in the East, South, Midwest, and West.

The women’s tournament’s regions are named for the cities where the final game is played.

Both tournaments culminate in the Final Four, which occurs in a predetermined location.

This year the men’s Final Four will be in Houston, Texas, and the women’s Final Four will be in Dallas, Texas.

Another year of upsets in March Madness as the men’s three number-one seeds and women’s two number-one seeds lost on the first weekend of the tournament.

On the men’s side, the Final Four are Flordia Atlantic, UConn, San Diego State, and Miami.

On the women’s side, the Final Four are South Carolina, LSU, Iowa, and Virginia Tech.

March Madness will continue to be a time of excitement for sports fans across the country as they watch their favorite teams compete for a chance to be crowned national champions.

Good luck to the teams and everyone’s brackets!
