About Mathzle
What is Mathzle?
Mathzle is a math game for grades 1–5, made for children aged 6–11. It runs in the browser on phones, tablets and computers, with nothing to install. Math is split into 6 worlds, each one strand of skills, following Vietnam's GDPT 2018 curriculum — the shared framework behind all three national textbook series.
Each lesson takes about 3–5 minutes and plays like a short level with Zle. We suggest about 15 minutes a day — enough for steady practice without long screen time. When your child gets one wrong, Zle hints step by step so they find the answer themselves. Skills they have learned come back for practice on a spaced schedule, so they stick.
