A mathematics investigation about 3D objects, embedded in a real-world context.

This open-ended mathematics investigation has been designed to deepen students’ understanding of 3D objects.

In this investigation, students must use their knowledge and understanding of nets, prisms and pyramids to design and build a model of a toy robot. Throughout the investigation, they will:

  • Draw a labelled, 2D diagram of the design (drawn to scale), which shows the various features of the robot.
  • Complete a materials matrix which explains which materials should be used for each part of the robot.
  • Build a coloured, 3D model of the robot which shows what the finished product might look like.
  • Design a persuasive poster to convince parents to buy the robot for their children.

This teaching resource includes:

  • teacher notes, detailing a range of important information about the investigation
  • a detailed description of the investigation for students, including step-by-step instructions
  • various planning worksheets and templates
  • reflection questions.
