In this worksheet, students perform a short experiment by cutting a cylinder to see the 2D shape that appears in the cross-section.

This worksheet is part of a larger unit designed to enhance understanding of 3D shapes for students in Year 6.

Curriculum Codes

AC9M6SP01 9

Compare the parallel cross-sections of objects and recognise their relationships to right prisms

ACMMG140 8.4

Construct simple prisms and pyramids


Construct simple prisms and pyramids

MA3-1WM old

Describes and represents mathematical situations in a variety of ways using mathematical terminology and some conventions

MA3-14MG old

Identifies three- dimensional objects, including prisms and pyramids, on the basis of their properties, and visualises, sketches and constructs them given drawings of different views

MA3-2DS-01 new

Investigates and classifies two-dimensional shapes, including triangles and quadrilaterals based on their properties

MA3-3DS-01 new

Visualises, sketches and constructs three-dimensional objects, including prisms and pyramids, making connections to two-dimensional representations



Have students bring in bananas or carrots to complete this activity (bananas preferable, as they can be cut with disposable knives) or bring marshmallows for the students. Otherwise, students can create cylinders using Play-Doh, allowing them to experiment more with different cuts.
