Lunch during school days

Like in America it is normal for a person to eat three meals a day in Germany. One of them being a hot/cooked meal, usually eaten at lunch time. Lunch is typically not served at school, so a German students either go home for lunch, to the city, or brings their own lunch from home. Lunch breaks for school are typically an hour and forty-five minutes, giving the student enough time to go home if they want.  During the 15 minute breaks between every 2 classes, student normally go out to the courtyard and eat a snack, such as fruits, vegetables, sweets, or sandwiches.  It is also normal for student to eat during class here, which is typically not allowed in America.
