All over the world, compulsory education is divided into three stages. The first stage is the primary education or elementary education, followed by pre-school education. Pre-school education is then preceded by secondary education. Most of the countries around the world have made primary education compulsory but there are some regions where they have granted the permission to the parents to provide primary education to their children. Age at which child transfers from primary to secondary or high school education is random, but mostly it happens when the child is about 11 or 12 years old. Though, in some countries the transitions occurs at the age of 14, because of the presence of middle schools in their education a system.

The main aim of primary education is to provide children with the basic knowledge of literature, mathematics and lay the foundation of other social sciences like geography and history etc. Usually children receive their primary education in elementary or primary schools, where they consistently advance in classes and finally reaching high school. Children are usually placed with one teacher who is responsible for their education for the whole year. That teacher is assisted sometimes by other teachers, for the subject areas that don't come under the expertise of that teacher.

In USA primary education is more commonly known as the elementary education taking place in elementary schools also known as grade schools or grammar schools. Primary education is comprised of either 6 or 8 grades and some times includes kindergarten as well. In elementary schools teachers usually imply looping strategy, in which the same teacher teaches the same group of students for two years. For example if a teacher teaches grade 2 the whole year, then the teacher would go on and teach those students in grade 3 as well. And after that the teacher would revert back to grade 2 and repeat the whole process again.

According to the National Association for Sport and Physical Education (NASPE), every child in USA has a right to have quality physical education and physical activity. Physical education is by far the best way to teach them the techniques and skills required for a healthy and active lifestyle by providing them physical activity. Teachers for Physical education assess different knowledge of the student and also their social and motor skills, and provide them the physical education accordingly. According to NASPE's recommendation elementary school's children should be provided with at least 150 minutes pf physical education per week, and as for middle and high school students the duration should be 225 minutes per week.

Bodily movement of any type is known as the physical activity. Keep the body active is the order of the day; this may be done by involving the body in recreational or sporting activities, which may include jumping the rope or taking part in sports like football, baseball or basket ball etc. Or daily activities like climbing up the stair case or even walking to the departmental store. When the body is active that raises the rate of heart beat, producing heavier than normal breathing. According to NASPE's recommendations a school-aged kid should avoid lengthened inactivity of the body and should engage itself in physical activities lasting up to 60 minutes, per day.
