How it is taught
The whole subject, in the order a child meets it.
- What is covered9 units and 62 lessons, every one of them in the book above: this is the whole of Algebra I in Grade 9, not a sample.
- Taught in orderA lesson unlocks when the one before it is mastered, and review is scheduled from what the child has actually shown rather than on a fixed timetable.
- Kept currentThese titles are read from the live curriculum, so what is in this book is what a Grade 9 student would work through today.
