Shape: Shadows

Australian curriculum number (ACMMG022)

In this task, students explore the relationship between three-dimensional objects and common two-dimensional shapes, through investigating the shapes of shadows cast by different 3D objects.

This sequence is for students who:

  • can name familiar 2D shapes and 3D objects and have a basic knowledge of the properties of these shapes and objects.
  • are familiar with the language associated with shapes such as sides and corners.
  • are familiar with the language of objects, including face, edges and corners.


Lesson 1: Shadows

Students explore the relationship between 3D objects and common 2D shapes. They investigate and predict the shape of shadows cast by different 3D objects. Students are also asked to consider different perspectives of a single object and the ways in which its shadow shapes may vary.
