Toolkits
Deep dives on the ideas that show up everywhere. Each one starts with why the idea exists at all — the problem it was invented to solve, what it actually does, and where it turns up outside a classroom — and then goes through it properly: the full explanation, the table you actually need, worked examples, and the mistakes that cost marks.
Measurement
Units are part of the answer
Carrying the units through a calculation catches most arithmetic errors before they reach the page. Conversion as algebra, why area factors square, and estimating with referents.

Algebra and number
Factoring is the skill that carries
The order of attack, what completely factored means, and the four later topics that do not work until this one is automatic.

How to use these
- Wondering why any of this is a thing? Read the opening section. It is the part a textbook usually skips.
- Stuck on a question type? Open the toolkit for that idea and find the worked example closest to it.
- Revising? Read the tables and try the checks, then go to practice questions to see whether it stuck.
- Revising for a final? There is no diploma exam in Grade 11, so your school sets the exam — the printable worksheets are the closest thing here to sitting one.
