Ready-to-use resources for teaching prisms to Years 7 to 10 (Grades 6 to 9). Lesson plans, worksheets, slide decks and assessments cover the properties of rectangular, triangular and hexagonal prisms, surface area and volume calculations, and constructing nets from 2D faces.
Curriculum-aligned coverage of the properties of prisms, surface area, volume and nets. Resources move from identifying prism types through to multi-step calculations involving composite shapes.

Real-world contexts that make prism geometry feel concrete: packaging design, storage container capacity, building cross-sections, ramps and architectural facades. Students see why surface area and volume matter outside the textbook.
Differentiated prompts let students enter at their level. Foundation tasks identify faces, edges and vertices; core tasks calculate surface area and volume of rectangular and triangular prisms; extension tasks tackle hexagonal and composite prisms, and convert between nets and 3D shapes.

Worked examples explain each step of finding surface area and volume so teachers can model the method, then hand it over to students. Solutions show the working, not just the answer, which makes reteaching straightforward.
Question banks and worksheets give students plenty of practice on volume of prisms, surface area of prisms, and matching nets to 3D shapes. Items are graded in difficulty so the same set works for revision, in-class practice or homework.
Tasks anchor prism geometry in design and measurement contexts students recognise — calculating how much paint covers a triangular roof panel, how much water fills a hexagonal planter, or which net folds into a given prism.

Lesson Plans for Surface Area, Volume and Nets
Lesson plans walk students through prisms in a clear sequence: naming the shape and its cross-section, identifying faces, edges and vertices, constructing nets from 2D faces, and then calculating surface area and volume. Each plan includes worked examples, diagrams of rectangular, triangular and hexagonal prisms, and discussion prompts so teachers can check for understanding before moving on. The structure works for an introductory lesson with Years 7 to 8 students and for revision blocks with Years 9 to 10.
Worksheets and Question Banks on Prisms
Worksheets and question banks cover the full range of prism tasks teachers need: identifying prisms from a set of 3D shapes, matching nets to their solids, calculating surface area using the area of each face, and finding volume using the cross-section × length formula. Questions are grouped by difficulty so a single set serves as in-class practice, homework or revision. Composite-prism and word-problem questions stretch students who have already mastered the basics.
Assessments and Applied Projects on Prisms
Assessments check whether students can apply prism geometry, not just recall the formulas. Tasks include short-answer questions, real-world problems (calculating the volume of a swimming pool with a trapezoidal cross-section, finding the surface area of a triangular tent), and applied projects where students design packaging, work out material costs, or construct a prism from a net. Marking guides and step-by-step solutions are included so feedback is quick to give.
