To begin with, eliminating recess is a good idea because it gives us that extra time to learn. We all know that the halls are crazy because of the limited time we have at our lockers, so we could use that time for lockers, because we all know some of our lockers are pretty small. Kids would have a lot more time to get organized, and so would the teachers. It would help to just eliminate recess and have more time!
Secondly, most bullying occurs on outdoor premises far from the teachers' views. So, eliminating recess would eliminate bullying as well and make the school a more fun and safer place.
