Odd One Out, provided by RISPs, helps students focus on mathematical properties to determine which of three numbers or expressions is the odd one out.

For example, given the triplet 2, 3, 9:
2 could be the odd...

Mathcentre provide these resources which cover aspects of vectors and are suitable for students studying mathematics at A Level, as well as those students for whom mathematics is an integral part of their course. Some of the topics covered include an introduction to vectors, calculating the vector and scalar...

This new curriculum resource from CensusAtSchool is presented at two levels of difficulty. This idea is relatively current as it links with the 'Da Vinci code' and the theory of the Vitruvian man as put forward by Leonardo da Vinci (1452–1519).

Due to problems in the manufacture of tinplate coils, the edge of the strip can be slightly longer than the centre. This causes a 'wave' on the wall of the coil but can be rectified by differentially stretching the strip to make the edges flat. Students are required to apply Pythagoras' theorem to find the radius...

In this resource students are given an image of a reciprocal curve, y=k/x. Two tangents to the curve are used, together with the coordinate axes, to form an 'arrow head' quadrilateral under the curve. The challenge is to determine the area of the quadrilateral.

The first step towards solving the problem...

A function is defined so that f(xy) = f(x) + f(y) for all positive integers x and y. Students are given the value of f(10) and (40) and are challenged to determine the value of f(500).

In each student worksheet contains different values for f(10) and f(40) but for...

This resource can be used as an introductory exercise into mathematical modelling. The problem is to decide on the winning team in a race. Students need to examine the data and decide on a model to determine the winner.

In this activity students explore the problem of analysing the effect of wind speed when temperatures are low requiring students to be able to substitute values into a formula. The formula for wind chill used in this resource depends upon the air temperature and the...

This resource, from Mathematics for Engineering Exemplars, shows the application of mathematics within the field of mechanical and electrical engineering in the power industry. When planning a wind farm it is important to know the expected power and energy output of each wind turbine to be able to calculate its...

This ebook provided by RISPs constitutes a collection of forty open-ended investigative activities for use in the A Level pure mathematics classroom. The book consists of two parts: the first part of the ebook lists all activities indexed by topic together with the teachers' notes. The second part advises on how to...
