Hello Minal and thanks for your post.
Having lived right next to a school during my teen years, I have to say that the experience was fairly loud and constant from 30 minutes before the school started to hours after the school ended. While you might think that the sound problems end on Friday, the truth is that most schools allow fields and facilities to be used during evenings and weekends, so there is often no break from the sound or activities at the school until evening descends. I will preface this by saying that I live in California where the weather is seldom colder than 40 degrees and we never get anything more disagreeable than a drenching downpour for a few days, so children here have far more opportunities than those on the East Coast to play (and make noise) outside.
At first, I'll admit that I wondered how my parents could buy this poorly located, noisy home--of course, I realize now that they could afford the home precisely because it was located so close to the school--but after about a year, I grew so accustomed to the sound that I did not even hear it. Today, I'm pretty "deaf" to sounds of traffic and trains and kids and planes, so, short of an earthquake, I'm as likely to sleep through loud outside noises without problems. However, not everyone is willing to make such compromises, so before you choose to purchase a home near an elementary school, its a good idea to spend a few hours at the home observing traffic patterns and listening to the sounds of the kids lining up in the morning, the recess in mid-afternoon, and the soccer matches on the weekend. This is the most effective way to determine if sounds within and without the home will negatively impact your lifestyle and enjoyment of the property.
