In the USA, many children need acarpool. A carpool is good for children who live far away from school and their schools do don't have school buses.

    Parents are often busy and they don't have enough time to drive their children to school every day. So they come up with a new idea. They use a carpool. That means that a group of students share a car and they go to school by car. There are usually four or five kids in a carpool. Their parents take turns driving the kids in their cars."

    Getting to school in a carpool is convenient for parents and students. Students can get to school easily if they choose to go in a carpool. What's more, it can help their parents save a lot of time and money.

    Teamwork is really important in the carpool because nobody wants to make the others late for class. If you sit in the car and wait for a classmate for a long time, you'll "probably get a little angry. But your carpool friends might feel the same way you keep them waiting.

    It's a great lesson in responsibility that you learn before school starts-in the carpool.
