It’s a cool morning on the school ground. Both the boys and girls are wearing their uniforms. They are talking happily to each other. It’s their first day at school after a long summer vacation. To prepare for new schooling, students often ask their parents to buy everything: notebooks, textbooks, pens, pencils, erasers... and a new uniform. School in Vietnam often starts in fall. The official date for the beginning of a school year is 5th, September. On that day, all the students are ready to come back to school. First days at schools are usually unforgettable. Students are excited to meet their friends and teachers again. Making friends to newcomers is a lot of fun, too. In their lessons, students have many interesting activities such as getting to know each other, playing games, singing songs, etc.
