This resource contains two excel files which encourage exploration of the background to Pythagoras' Theorem and give practice in its application. Each file contains the same nine sheets of questions which may be suitable for use in the classroom.

This interactive resource, produced by the University of Leicester, is designed to enable students to explore what is meant by a quadratic equation, the meaning of the coefficients of a quadratic equation and to be able to solve quadratic equations. An introduction page gives examples of where quadratic equations...

This resource contains four excel programs with interactive spreadsheets dealing with topics relating to quadratic expressions, their graphs and solving quadratic equations.

The different types of quadrilateral are illustrated in the first seven interactive sheets of this excel file. Examples of each type of quadrilateral are shown and then further examples illustrated on a coordinate grid. The next sheet is more like a quiz as...

This collection of interactive excel sheets look at radians, arc length, sector area, converting to and from degrees, and other related problems.

The first sheet displays a sector of a circle and corresponding...

This interactive file shows the graphs of functions and the graph of the corresponding reciprocal function. It begins with the graph of a linear function where the gradient and intercept can be changed. The reciprocal is plotted on the same diagram. The next two sheets...

This activity provides the opportunity for students to appreciate how mathematics plays a part in everyday life. The town council has allocated £100,000 to spend on reducing the number of deaths and serious injuries due to road accidents. Students are expected to adopt the role of planners who work in small teams...

This is a series of interactive excel sheets exploring linear regression.

The first sheet plots a scatter diagram and line of best fit for a small set of bivariate data. The mean and product moment correlation...

In this resource from the DfE Standards Unit, students interpret 2D representations of 3D shapes, analyse 3D shapes using plans, elevations, and isometric drawings and develop their reasoning ability in spatial contexts. Many students may have met these ideas before, but they may still experience difficulties in...

This engineering resource, produced by Mathematics in Education and Industry (MEI) for the Royal Academy of Engineering, asks the question: how can production outcome data from a manufacturing process be analysed to optimise the process? Students consider the outputs of resistors to see the outcomes form a normal...

This resource contains two interactive excel files which deal with rounding of discrete and continuous variables and pose problems involving practical examples of calculations using rounded values.

Rounded Numbers: Bounds The first interactive sheet shows two numbers rounded to the nearest...

This series of twelve interactive excel sheets explore rounding numbers. New questions can be generated each time by the click of a button. To check the answers click on the smiley face.
