Diagram, givens, target
Mark every given on the diagram and state the target clearly. Start from a relationship that connects exactly those quantities.
KS3 Year 7 / Mathematics / Curriculum
Geometry and measure: structured theory, worked examples, answered practice, and a mastery checklist for KS3 Year 7.
Unit
The essential chapter ideas in a clear sequence before practice.
Mark every given on the diagram and state the target clearly. Start from a relationship that connects exactly those quantities.
Every geometric step needs a property, theorem, or definition. A result without justification is not a complete proof.
Length, area, volume, and angle use different units. Round only at the end and keep sufficient intermediate precision.
Mathematics
Follow the method step by step and check why every step is valid.
A right triangle has perpendicular sides 15 cm and 20 cm. Find its hypotenuse and area.
Mathematics
Start from the board specification and work topic by topic before full papers.
The structure follows the official textbook layout and is used to organise study.
Hypotenuse 25 cm, area 150 cm².
Before calculating, explain the key idea from “Angle facts” and which conditions must be checked.
The answer should show not only which rule is used for “Angle facts”, but also why it is valid here.
Geometry and measure
Try independently, use the hint if needed, then open the answer guide.
1. Explain the idea and give one correct foundation example for “Angle facts”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Angle facts”, shows equivalent steps, and includes a final check.
2. Solve an application and show every intermediate step for “Angles on a straight line”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Angles on a straight line”, shows equivalent steps, and includes a final check.
3. Compare a correct and an incorrect approach and justify the difference for “Angles around a point”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Angles around a point”, shows equivalent steps, and includes a final check.
4. Create a short exam-style question and check your answer for “Vertically opposite angles”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Vertically opposite angles”, shows equivalent steps, and includes a final check.
The areas that usually create mistakes or need extra revision.
Where to start: textbook, daily material, PDFs, videos, and worked examples.
Targeted practice before full tests so coverage is clear.
How to measure progress in this chapter and when it enters a cumulative mock.
