Welcome to Mastery Maths
A mastery maths programme for Years 1–6, inspired by the concrete–pictorial–abstract approach. Every lesson teaches one idea properly — pictures and visual models first, then guided steps, then challenging word problems — so understanding comes before speed.
Your child logs in with their KAOO username and PIN — set up on the Children page of the parent portal.
Every lesson has six steps
1 · Discover
Meet the idea through a picture or story problem — see it before you solve it.
2 · Learn
The method, step by step, with visual models and worked examples.
3 · Trace
Follow a worked solution closely, then try one just like it.
4 · Solve
Your turn — with hints if you slip, and the full working revealed if you need it.
5 · Challenge
A multi-step problem that stretches the idea further.
6 · Practice
20 questions from fluency to word problems, with a wrong-answer review at the end.
