Chinese Postman Problems

In this activity from the Nuffield Foundation students use the Chinese postman algorithm, also called the Route Inspection Problem, to solve practical problems. The College Open Day problem provides an introduction to the concept, and asks students to investigate the minimum distance someone would have to travel to...

Cable TV

This activity from the Nuffield Foundation shows students how to use Kruskal’s and Prim’s algorithms to solve minimum connector problems. A cable TV company wants to lay cables to connect the towns, laying the cable along the roads shown on a map of the Isle of Wight. They want to connect all of these towns to...

Coastal Erosion

The Nuffield Foundation provides this resource which shows students how, given a set of measurements along an irregular coastline, it is possible to approximate the area of land which is lost to coastal erosion over a period of time. Coastal erosion A - this activity uses the context of coastal erosion to introduce...

Derivative Matching

The Nuffield Foundation provides this activity which can be used to review students' knowledge of the derivatives of quadratic and cubic functions and their graphs. The slideshow provides an introduction by considering a quadratic example and a cubic example.

There are 12 sets of cards, each set containing a...

Ozone Hole

The Nuffield Foundation provides this activity where students suggest types of function to model ozone hole data, before using a graphic calculator or spreadsheet to find at least two particular models. They then consider how well their functions model the data and what they predict for the future. The slideshow...

Gas Guzzlers

The Nuffield Foundation provide this activity which uses graphical methods to find a suitable model to connect two sets of data. There are a variety of ways in which the data could be used, depending on the focus required. It is possible to use a log graph to find an exponential model, which is the intended focus...

Climate Prediction

The Nuffield Foundation provides this activity which students use to create spreadsheets that model what would happen to the temperature of the Earth if there were to be a sudden change in the amount of radiation entering or leaving the planet. Students then investigate polynomial and exponential functions to find...

Cup of coffee

This resource is part of a collection of Nuffield Maths resources exploring Algebra. The demand is roughly equivalent to that in GCE A level.

In this resource students model data measuring how long caffeine from tea, coffee or cola stays in the human body’s bloodstream. This involves drawing graphs, then...

Coughs and sneezes

This resource is part of a collection of Nuffield Maths resources exploring Algebra. The demand is roughly equivalent to that in GCE A level.

In the ‘Coughs and sneezes’ resource students have to use polynomial and trigonometric functions to model the number of people suffering from a cold over several weeks...

Completing the square

This resource is part of a collection of Nuffield Maths resources exploring Algebra. The demand is roughly equivalent to that in GCE A level.

The resource includes matching cards to practise completing the square and helps relate the competed square form to the graph of the function.
