After the lessons in the morning end, students on duty head for the pantry to get their food containers and carry them to their classroom, where they are supposed to eat lunch. In the second picture here, you can see numbers like 3-3 and 4-3 on the side of the blue containers. These show their grade and classroom. For example, 4-3 means the 3rd classroom of the 4th grade. In many schools, the students are required to wear a white coat. All students, boys and girls, take turns doing this job in the weekly rotation. Even first graders do most of this by themselves.
