School Grounds em wide, around the yard Poinciana trees and ancient eagle shade cover, with flower beds and lawns green. Listed under the tree row of stone for us to read books and talk after each lesson. The classrooms are full of tables and chairs, cabinets for learning and also exhibited the post office corner, nicearle.
