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.
Shape and space
Right triangles everywhere
The Pythagorean theorem as a tool: finding a missing side, checking a square corner with 3-4-5, screen sizes, ramps and shortcuts, and the diagonal of a box face.

Number
Thinking in proportion
Ratio, rate, percent and scale as one idea: two quantities that grow together, equivalent ratios, unit rates, percent as a ratio to 100, and scale drawings.

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.
- Reviewing for a unit test? There is no provincial test in Grade 8, so your teacher sets the tests — the printable worksheets and a mixed quiz are the closest thing here to sitting one.
