                       Primary schools in England
                        Primary schools in England
     In Great Britain school begins at the age of four or five. Many boys and girls usually leave school at the age of sixteen.
     In England the school year begins in September, but not always on the first day of the month.The weather is usually fine. It is warm. The sky is often blue and the sun is bright. School seldom begins on Monday because the English think that Monday is not a good day to start school.
     Little children go to school with their parents. They look so clean and nice and don't have any bags or books with them. Pupils will get them later. They will get exercise books, pencils, pens, rulers and rubbers too.
      Classes usually begin at nine. Pupils have a break at 10.30 and may have a drink of milk or orange juice. At half past twelve or at one o'clock they usually have lunch. Their classes are not always formal. They often sit on the carpet on the floor and listen to their teacher. They draw or play games. They often look at the animals they have at school — hamster, rabbits or hares. Sometimes there are birds or fish in their classrooms.
     English pupils often play outdoors.

     English children have classes five days a week. Classes are  usually over at four o'clock and then the pupils go home. Saturdays and Sunday are their days off.
     Schools in England have names, not numbers.

     At the age of five primary school children go to infant. They play different games, run and jump.
     They sing songs, dance and play a lot. Infant pupils learn how to use money in their classroom shop. They look at the pictures in interesting books, draw pictures in pencil and color them. They learn how to get on with other children. Their classes are informal, but they learn to read, count and write a little too.     When children are seven they go to junior schools. In England children spend six years in primary school. When pupils are eleven or a little older primary school is over.
     Junior schools are real schools. Pupils sit in rows and follow a regular timetable. Their subject are: English, Maths, History, Nature Study, Geography, Art, Music.
They visit different museums and other famous and interesting places.
