Curriculum

Every topic, P1 to P6

From basic addition to percentages, speed and 3D shapes. Each question is written for one topic, never pulled at random.

Learning loop

Hints, not answers

A wrong answer brings a hint, not the solution. Mistakes come back later for review until they stick.

Diagrams

Not just sums

Shapes, charts, measurement and direction questions that need a picture — the kinds found in real school papers.

New

Daily speed maths

100 quick calculations a day, the same set for everyone in the grade. Scored on accuracy and speed against a target — no leaderboards.

Parents

See the weak spots

A PIN-protected parent area shows what your child did, which topics are weak and recent mistakes. Optional daily email.

Languages

Chinese, English or both

Set per child. One tap switches the current question to the other language.
