# Delivering water

TLF ID M017776

This is a mathematics unit of work about water: its world-wide availability and use; the time spent carrying it; the best shape for water tanks; and the area of land taken up around tanks and in paths and ditches to water sources. Intended for years 9 and 10 and written from a global education perspective, the resource consists of three single- or multi-lesson activities, titled: Daily water use; Length and breadth; and Volume of the water tank. Student activities involve a range of calculations, including the volume and surface area of tanks of various shapes, and making observations and recommendations. The resource includes diagrams, tables and links to websites and other resources.

#### Educational details

Educational value
• This is an excellent resource for the Measurement and Geometry strand in the years 9 and 10 mathematics curriculum. It is particularly relevant for year 9 content descriptions that refer to: calculating the areas of composite shapes, calculating the surface area and volume of cylinders; and solving problems involving the surface area and volume of right prisms. It is also useful for the year 10 content description about solving problems involving surface area and volume for a range of prisms, cylinders and composite solids.
• Activities in the unit of work support student development of a number of the general capabilities, particularly Numeracy and Critical and creative thinking. They are especially relevant to the organising elements of using spatial reasoning and measurement in Numeracy and the inquiring - identifying, exploring and organising information and ideas element in Critical and creative thinking.
• Although there is no reference to geography in the unit, its global perspective provides an opportunity for integrating mathematics and geography in year 9. The unit asks students to calculate the amount of time taken to carry water; students also calculate the surface area of land used in pathways and pipe-carrying ditches to and from water sources. These tasks may connect well to the 'Biomes and food security' geography unit of study, particularly its content description about the challenges to food production in various areas of the world, including shortage of fresh water and competing land uses.
