The Rainbow series is specially designed for kindergarten children, covering subjects such as English, mathematics and science, and is suitable for children from lower to higher classes. A major feature of the Rainbow series is that each stage is divided into a Student's Book (teaching materials) and an Activity Book (exercises). The teaching materials use interesting facts, colorful charts and examples close to life, allowing children to happily understand the world. The workbooks contain simple questions, dialogues and examples from everyday activities, which encourage children to explore the world and teach them to put the knowledge they have learned into practical use.
