# 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.
• Create the correct size box that would house your model would fit into. Use a suitable net. You will need to know the volume of your model in the standard unit of cubic centimetres.
Body:
2. Rover and assist where needed.
3. Pull out focus groups for various parts of the task (where needed)
4. Remind students to think about:
• Who will buy it? A boy or girl? What age?
• How will you advertise it? Photos, videos?
• What profit would you expect to make?

Conclusion:

Discuss with your students and ask them to record what they have learnt about:

• Geometric and spatial reasoning.
• 2D images of 3D objects.
• Problem solving and logic.
• Money calculations and conversions.
• Volume and nets.
• Marketing and finance
• Visual sequencing.

# Assessment:

• Collect responses to the above conclusion.
• Photographs of toy
• Anecdotal discussions with students

# Resources:

• Pens/Pencils
• Workbooks
• Cameras of some sort (digital/ipad/iphone, etc)
• Unifix or connector blocks
