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.
