The playgrounds have been given new play equipment as well as new trees and bushes
Bernard Brenanan, headteacher at St Bernard's Primary School, says: "Children come into class ready to work now, instead of being angry."
It's not just the kids who benefit either.
Around 70% of people in the area think the new playgrounds are a better place for local wildlife.
And, for once, the staff are happy too.
Nearly all the teachers said that the new playgrounds made them less stressed.
That can only mean they'll be in a better mood in class!
