Summary:

In this lesson, students design, create, record, market and finance a new toy.  The go through a vast amount of the curriculum while doing so and have fun developing their product. A lesson that works well with pairs or individuals, it is highly engaging through its hands-on and real-life connections.

Australian Curriculum Links:

  • Use efficient mental and written strategies and apply appropriate digital technologies to solve problems(ACMNA291)
  • Connect three-dimensional objects with their nets and other two-dimensional representations(ACMMG111)
  • Select and apply efficient mental and written strategies and appropriate digital technologies to solve problems involving all four operations with whole numbers (ACMNA123)
  • Multiply decimals by whole numbers and perform divisions by non-zero whole numbers where the results are terminating decimals, with and without digital technologies (ACMNA129)
  • Investigate and calculate percentage discounts of 10%, 25% and 50% on sale items, with and without digital technologies (ACMNA132)

Lesson:

Introduction:
  1. Introduce students to the create task of designing a toy. Ask them to think about the jobs that would be involved in creating a toy and marketing it for sale in Australia.
  2. Explain what to do:
  • Students work in pairs.
  • Using no more than 40 blocks build a model, eg a dinosaur, truck, helicopter, robot.
  • Record what colours you have used and how many.
  • Draw it / photograph it.
  • Take it apart photographing the step by step stages of building it.
  • How much will you charge for your creativity? Decide the cost of one block and use multiplication to calculate. Factor in labour time.
