Here is a bus made from Lego. What mathematical questions could you explore?
![Lego bus made from red and blue bricks, viewed from the side.Two wheels are visible at the bottom; perhaps there are two more wheels on the other side of the bus. The blue bricks make three 'windows' at the front, back, and middle.](https://alisonkiddle.co.uk/wp-content/uploads/2023/08/Lego16-1024x576.jpg)
How many wheels?
How many windows?
Might there be wheels and windows that you can’t see?
A bigger bus might have more wheels and windows. Can you draw or make some more Lego buses? How many windows would there be? How many wheels?
