Math

Students investigate how three-dimensional objects can be represented as a series of two-dimensional layers.

Concepts at a Glance

Students will:

Explain the basic principle of additive manufacturing.
Identify cross-sections of common three-dimensional shapes.
Represent a 3D object as a sequence of 2D layers.
Recognize how complex objects can be built from simple geometric forms.

Activity Instructions

Students investigate how three-dimensional objects can be represented as a series of two-dimensional layers. Through cross-section activities, they explore how additive manufacturing works and develop spatial reasoning by analysing, drawing, and reconstructing objects layer by layer. The lesson introduces the fundamental concept behind 3D printing while encouraging students to think like designers and engineers.
