A blog about teaching and learning in a maths classroom.

Matchbox cars, specifically that brand, have a scale written underneath.

I've always wanted to do something with that.

Here are some questions I might ask, before any calculations are done:

- Which is longer in real life, the Honda or the Volkswagen?
- Without calculating, estimate the real length of the fire truck.

Then,

- Find the real length of all.

Honda Insight 2010 | Volkswagen Bus | Lexus GS430 | Fire truck | |
---|---|---|---|---|

Scale | 1:62 | 1:59 | 1:64 | 1:123 |

Model length (mm) | 69 | 72 | 75 | 74 |

Calculated length (mm) | 4 278 | 4 248 | 4 800 | 9 102 |

Real-life length | 4 390 | 4 505 | 4 826 |

What about this Matchbox plane? It has no scale. I measure the model's length as 106 mm. The model is a Cessna Citation X with a length of 22.05 m.

Therefore, the scale should be 1:208.

Any other good questions? What else should I do?
