Hockey is a team sport. You have ice hockey and hockey on a field. I am going to tell you something about field hockey.

Since a long time ago, people play ball-sports with the help of a stick and a ball. It’s calls hockey.
The field
The most of the fields are bogus-grass. But by some clubs there are ordinary fields, made of grass. The field is 100 yard long and 60 yard wide. In the mid of the field is a line. On each side of the field is a 25-yardline. There is a circle from 16 yard out of the goal on each side of the field. 7 yard in the circle out of the goal is a little point. That is for a free push. When you try to make a goal out of the circle and it is a goal, it doesn’t count.
Rules
Hockey is a team sport. Two teams play against each other. Every team has 11 players. One of them is the keeper. You must get the ball in the goal of the other team. In a match there are 2 umpires. They are divided in the field. One umpire on that side of the field, the second umpire on the other side.
You have to keep you stick under you shoulders, don’t touch the ball with your feet, arms, legs or any other part of the body, because then it’s shoot. The other team has a free ball. You have to play it with the other people of your team, it’s simpler and you earlier can get a goal. It is also nicer for the other players of your team.
Framing
On the middle line of the field there is 1 player. Right en left from that player are 2 other players. Behind those 3 players are 3 other players. They are the middle players. And behind those middle players are 3 back players. There is one player in the goal that is the keeper. Before the keeper is one player, he is the last player in the field.
Hockey stuff that you need
You really need a teeth-protector. There are shoes made for hockey, the underside has some little spikes so you can’t slip. Of course you need a stick. There are a lot of brands. Grace, Dita, Stag and a lot more.
The keeper has extra protection like a helmet (it also protect their face), a body protector and legs protectors. It’s not heavy because the most is made of foam that is really lightly.
