Ice hockey is a sport that is played by two teams on ice. The players wear ice skates on their feet and can skate across the ice at very high speeds. They hold hockey sticks, which they use to push, shoot or pass a puck around the ice. The players score by shooting the puck into a net; the goaltenders try to stop them. Six players on each team play at once, but a whole team has over 20 players. Each team has 2 defenders, 3 forwards, and a goalie on the ice at a time. When a player breaks a rule, a referee calls a penalty, and the player has to sit in a penalty box for 2-4 minutes. While the player sits in the penalty box, their team has to play without them, and will have fewer players on the ice until the penalty is over.

Hockey is played by both men and women at the Olympic games, and at world championships. Ice hockey began in Canada in the 19th century. There are two types of penalty: The major and the minor. The minor is the main one the referee will call during a game and the players have to go in the penalty box for two minutes. The major is when players fight with each other or when someone did something very dangerous. Most of time players are kicked out of the games but in a fight they only get 5 minutes in the penalty box. In the National Hockey League (NHL) there are four referees. Two lineman and two head referee. Only head referees can call the penalty. They can be recognized by the orange armband on their arm. In the major league, the game is separated into three periods of 20 minutes. For the minor league, the time can be different for each category. Each period starts after the face-off. A face-off is when two teams are in position around the face-off circle. Then, the referee drops the puck between the players who play center. There are 6 different positions: center, right wing, left wing, right defense, left defense and goalie. The play is over after a whistle of any referee. After a whistle-blow, the time stops running. Each team can have a maximum of 20 players, including two goaltenders who have a zone to defend. Each team has one captain and two or three assistant captains. The ice is separated into three zones. Each zone is marked by lines. The center zone is between two blue lines and team zones are between one blue line and the end of the ice. The lineman can whistle for two reasons: icing and offside. An icing is when a player throws the puck into the zone before he crosses the red line (center line) and an offside is when a player enters the zone before the one who has the puck enters with it.
