3D Shapes and Nets
Year 6 students identify and describe three-dimensional objects including prisms and pyramids, and connect 3D shapes to their two-dimensional nets.
What You Need to Know
Key Concept Diagram
Prisms have two identical parallel bases joined by rectangular faces, and are named by their base shape
Pyramids have one polygonal base with triangular faces meeting at an apex
A net is a flat arrangement of faces that can be folded to form a 3D shape
Faces, edges, and vertices follow Euler's formula: F + V − E = 2
Key Vocabulary
Prism
A 3D shape with two congruent parallel polygon bases and rectangular lateral faces
Pyramid
A 3D shape with a polygon base and triangular faces that meet at a point (apex)
Net
A 2D pattern that can be folded to make a 3D solid
Vertex (Vertices)
A corner point where edges of a 3D shape meet
