Must know

1Perimeter is boundary length of a closed figure; circumference is boundary length of a circle.
2Add side lengths for polygons and use circumference formula for circles when required.
3Circumference means perimeter of a circle.
4Boundary length uses linear units.

Formula / process

1Perimeter and Circumference questions become easier when the representation and rule are chosen before calculating.
2Keep diagrams, signs, units, and final statements visible.
3Area of Plane Figures questions become easier when the representation and rule are chosen before calculating.
4Rings and Combined Figures questions become easier when the representation and rule are chosen before calculating.

Exam traps

1Students often use square units for perimeter.
2Boundary length uses linear units.
3What unit should circumference have?
4Students often use slant side instead of perpendicular height.

Answer frame

Start with the exact keyword or formula before adding explanation.
Use one example, diagram cue, observation, or substitution to support the answer.
For 3 marks: definition, reason, and one supporting point.
For 5 marks: setup, method/process, example, conclusion, and final check.

Notes Write answers

Shape cutouts with coloured string tracing rectangle, triangle, square, and circle boundaries to show perimeter and circumference.

ModelPerimeter and Circumference

Perimeter and Circumference model

Perimeter is boundary length of a closed figure; circumference is boundary length of a circle.

Given

The values, diagram, expression, or data from the question.

Rule

Add side lengths for polygons and use circumference formula for circles when...

Check: Show the representation before the calculation.

Rectangle, triangle, parallelogram, and circle cutouts on a square-tile mat showing area as surface coverage.

ModelArea of Plane Figures

Area of Plane Figures model

Area measures surface covered by rectangles, triangles, parallelograms, circles, and combined figures.

Given

The values, diagram, expression, or data from the question.

Rule

Choose the formula matching the figure and keep square units.

Check: Show the representation before the calculation.

Layered circular cutouts, overlapping shapes, and coloured tiles showing rings and combined figures.

ModelRings and Combined Figures

Rings and Combined Figures model

Rings and combined figures are solved by adding or subtracting areas of simpler shapes.

Given

The values, diagram, expression, or data from the question.

Rule

Split the shape into known parts and decide whether to add or subtract.

Check: Show the representation before the calculation.

FlowPerimeter and Circumference

Perimeter and Circumference solving flow

A compact flow for perimeter and circumference problems.

Read

Underline the required result.

Represent

Use a number line, expression, formula, graph, or diagram.

Check: Show the representation before the calculation.
