Cars In A Garage

Task 2 ... Years 2 - 10

Summary

Cars and garages are familiar to students of all ages. In this task the challenge is to find all the ways to park the cars in the garages.
  • How many parking solutions are there?
  • How do we know when we have found them all?

Materials

  • 4 toy cars
  

Content

  • counting
  • 1:1 correspondence
  • mathematical language of position and order
  • visual patterns, including patterns of colour
  • multiplication, multiplicative thinking, multiplication principle of counting
  • permutations & combinations,
  • logical reasoning
  • problem posing and solving
  • recording mathematics

Iceberg

A task is the tip of a learning iceberg. There is always more to a task than is recorded on the card. 		   

Possible iceberg investigations for this task are:

  • What happens if we change the number of cars?
  • What happens if we change the number of spaces?
  • If I tell you any number of cars are parked in the same number of spaces can you tell me how many parking solutions there are?
  • What happens if there are more spaces than cars?
  • What happens if we make conditions on where particular cars can park?

Whole Class Investigation

Tasks are an invitation for two students to work like a mathematician. Tasks can also be modified to become whole class investigations which model how a mathematician works. 		   

The whole class lesson for this task is detailed in Maths300 Lesson 128, Cars in a Garage. This lesson also extends the investigation with software. You will need at least three model cars (or substitute) per pair of students. If you have Poly Plug you can use them as a red car, a yellow car and a blue car, but you will need something else to use as a fourth and fifth car as the problem deepens. The Maths300 lesson provides sufficient material to explore up to five cars. The 'cars' have to be printed and cut out.
