Shape, Space and Measurement
Overview
This unit develops students' understanding of geometry and measurement. Students will explore 2D and 3D shapes, learn about symmetry, calculate perimeter and area, and work with angles, time, and money. Through hands-on activities and real-world problem-solving, students will appreciate how geometric and measurement concepts help us understand and navigate the physical world.
Key Concept
Form — The shapes and structures of objects determine how they look, function, and relate to each other in space.
Related Concepts
- Space — The dimensions and arrangements in which objects exist and move.
- Measurement — Quantifying attributes such as length, area, time, and value.
- Patterns — Repeated arrangements and regularities in shapes and measurements.
Global Context
Orientation in Space and Time — How do we use shape, space, and measurement to understand our position in the world and organise our lives?
Statement of Inquiry
Shapes, patterns, and measurements help us understand and organise the physical world.

Summative Assessment
Shape and Measurement Project: Students will design a dream room or small building, creating a labelled floor plan with accurate measurements, calculating perimeter and area, identifying 2D and 3D shapes used, and incorporating symmetry in the design. The project must include a written explanation of the mathematical choices made.
Measurement Investigation: Students will complete a practical measurement investigation where they estimate and then accurately measure length, mass, and capacity of various objects, analysing the accuracy of their estimates.
