Answer:
Easing troubles of recess time
Due to the increase in the total number of students, school life has become relatively difficult for all the students in general, especially during recess time. The availability of food depends on how early you reach the canteen. Food mostly finishes before half of the students even reach the canteen after their classes get over. This is quite the concern that has arisen as of late.
Certain suggestions that can be implemented to ease this issue are:-
1. Having different recess time according to the classes on each floor. This will make it easier for the students to navigate through the canteen with the issue of overcrowding.
2. Increasing the stock of food in the canteen.
3. Having another canteen in the main hall along with the one in the main compound.
These remedies can help make the break time easier for the students and the staff as well. The reduction in overcrowding will help the students to have recess without any chaos and confusion and also prevent the school from getting complaints from the students or parents.
