Elementary school is one of the base educations we have as we were a child. There are two types of elementary school, those are Public School and Private school. Personally, I was study in Private elementary school which was located in Yogyakarta, Indonesia. It was called SD Kanisius, the school was a catholic-based education school which most of the students are non-moslem. The school contains 6 classes only with each class defined each grade in Elementary School education system, for instance let’s say it is “Class 1” so the class belongs to the first grader and so on.
