Fire Hydrants

This Nuffield activity asks students to experiment with the placing and number of fire hydrants required in a city with square blocks that form a rectangular grid.

Key processes developed in this investigation are:

*Representing - diagrammatic representation and moving to more abstract mathematical methodology.

*Analysing - considering different arrangements, making accurate mathematical diagrams, working systematically, identifying patterns and beginning to make generalisations.

*Interpreting and evaluating - considering findings to form convincing arguments, and relating these to the context of the task and diagrams/patterns found and justifying findings.

*Communicating and reflecting - explaining the approach taken and outcomes achieved at each stage of the work.
