American students take part in different activities at recess. The energetic students often play basketball, but they never have time to play a whole game. They just practice scoring goals. This is called “shooting some hoop”. Many of the students listen to music. Sometimes they read or study at the same time. Some of the children, mainly boys, swap baseball cards. These pictures of baseball players come in packages of candy. They swap cards with their friends, so they get the ones they want. Eating and talking with friends are the most common ways of relaxing at recess. These activities are the same all over the world.
