Self-study sequence
The online course supports students after they have engaged with the workbook. The platform is structured to encourage independent thinking before additional support is opened.
- 1Read the workbook teaching notes
- 2Answer the guided question before the explanation
- 3Attempt the chapter exercises independently
- 4Check final answers in the book
- 5Read the future connection for the concept
- 6Use worked solutions when stuck

Built from the future backwards
Each chapter page now identifies what the current topic prepares students for later: algebra, functions, trigonometry, calculus, statistics, proof, modelling or exam synthesis.
Guided mathematical thinking
The standard lesson pattern is question, pause, student thinking, explanation, practice and feedback. The platform is being shaped around active reasoning rather than passive video watching.
