In Australia, many families live a long way from a town, so the nearest school is often very far away. For this reason, many children attend a very different kind of school of the Air because the students have classes over the radio. Most areas have a school like this for children between 4 and 12 years old. They study at home but they are still members of the class. The children have radio lessons with their class three times a week. Each lesson lasts about 30 minutes. Students also have a 10-minute private lesson with their teacher once a week. The school provides the radio, books, videos and other resources. The children send their work to the teacher once a week. The children’s parents help them to do their work at home.
