About Liu Lao Shi Apps

Liu Lao Shi Learning Apps is an educational website for children, parents and teachers. We build interactive web apps that support primary school learning with simple visuals, guided steps and focused lesson practice.

Our goal is to make revision more engaging. Instead of showing one large list of worksheets, we organise practice into specific lessons such as Year 3 Addition, Year 5 Vocabulary Unit 1 and Chinese Hanzi practice.

We continue to add new apps over time so families can find helpful learning tools for different subjects and year levels in one place.
