Shape: Shadows

Australian curriculum number (ACMMG022)

In this task, students look at how three-dimensional objects are composed of two-dimensional shapes.

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

In this task students explore the relationship between three-dimensional objects and common two-dimensional shapes. They investigate and predict the shape of shadows cast by different three-dimensional objects. Students are also asked to consider different perspectives of a single object and how its shadow shapes may vary.
