Nets and Surface Area of Prisms and Pyramids — Interactive Lesson (Ages 11–14)

Still struggling to picture which faces make up a 3D shape’s net? This substantial 29-slide interactive lesson gives pupils extensive, self-marking practice using nets to calculate the surface area of prisms and pyramids.

Mastering Nets and Surface Area in KS3 Maths

Pupils practise visualising nets and using them to calculate the surface area of prisms and pyramids, building the fluency within the KS3 National Curriculum area of geometry. Covering both shape families together, rather than as two separate topics, helps pupils compare the two net structures directly and apply the same underlying method to each.

What’s Included

• 29-slide interactive lesson covering prisms and pyramids
• Genuine coverage of both nets and surface area calculation
• Self-marking activities with instant feedback
• Extensive practice given the substantial slide count

Key Benefits for Students

• Builds genuine visualisation skills for 3D nets
• Instant feedback confirms correct working straight away
• Extensive practice across a substantial number of slides
• Covers two related shape families in a single resource

Why Teachers Love It

• No prep — ready to use on any interactive whiteboard
• Self-marking format supports independent practice
• Substantial enough to carry a full lesson on this topic
• Genuinely covers both prisms and pyramids, not just one
• A dependable resource for a genuinely visual, spatial topic

• Constructing and Bisecting Angles — Interactive Lesson (Ages 14–16)
• Substitution into Formulae and Expressions — Interactive Lesson (Ages 11–14)
• Pythagorean Theorem: Finding Side Lengths — Interactive Lesson (Ages 11–14)

A strong addition to any KS3 geometry topic, giving pupils genuine practice with two related 3D shape families in one resource rather than needing a separate lesson for each. Comparing the two nets side by side also helps pupils generalise the underlying method rather than memorising each shape in isolation from each other entirely, which is easily done.
