Nets for Prisms and Pyramids — Year 5 Mathematics

Teach learners to connect the faces of a solid to a net that can fold. This five-lesson sequence moves from triangular prisms and square-based pyramids through matching edges, checking invalid candidates and physically testing a model. A three-page teacher guide provides preparation, lesson flow, game key, access options and marking guidance.

The 25-page Unit Plan PDF has a colour face-inventory display, 12 model cards, guided/core/transfer practice with position-matched answer pages, a 12-card partner comparison kit, two rehearsal tasks with answers, an independent model-building assessment with a marking page, and a four-criterion evidence rubric. Colour supports display and activity pages; practice, assessment and rubric are low-ink black and white.

Learners finish by drawing and building a triangular prism and a square-based pyramid, justifying face and joining-edge relationships, and explaining an invalid candidate or revision. The physical fold verifies closure; face count alone is insufficient. An editable 18-slide PowerPoint presentation and editable 26-slide PowerPoint quiz support teaching and checks for understanding.

Learning focus

Count and identify prism and pyramid faces; match joining edges; predict, build and test nets; explain gaps, overlaps and revisions.

Classroom use

Five 45–60-minute lessons. Use paper or card, rulers, age-appropriate scissors, tape or glue, and physical solids; supervise cutting. Access options include larger ready-cut faces, physical models and recorded oral or pointing explanations while keeping the edge decision with the learner.
