Aoshu Primary Math

This is one of the most-visited primary school math enrichment websites in China, launched in 2004 and aimed at students from grade 1 to grade 6. The main focus is on Olympic math (aoshu) competition problems and thinking skill development. Users can browse problems by grade level and topic, with detailed solutions and answer keys provided for most questions. Beyond math, the site also covers Chinese language, English, and composition subjects. A separate section tracks key middle school admissions policies across major Chinese cities, helping parents prepare for the primary-to-secondary school transition. The platform updates content daily and sees heavy traffic during exam seasons. Parents frequently use it to find supplementary exercises for their children, and teachers sometimes refer students to specific problem sets. The site is free to access with optional premium features, and its math competition section is widely cited in parent forums and educational blogs across China.
