This excel file allows students to explore the successive terms of a Geometric Series. The first term and the common ratio can be altered and the successive terms and sum of the series shown on bar charts. The formula for the sum of a Geometric Series is derived and the...

This series of interactive excel sheets help investigate geometric series and progressions.

The first sheet generates the terms of a geometric progression, for |r| ≥ 1, and the value of a further term. A new sequence...

This series of excel interactive sheets look at the golden ratio.

The first two sheets investigate the ratio of each pair of consecutive terms in the Fibonacci series, and what happens to the ratio as the sequence...

This excel program contains a series of interactive spread sheets designed to explore the concept of a gradient of a curve.

The first activity illustrates that the gradient of a function, at a point P, is the gradient...

This excel program contains a series of interactive spreadsheets designed to explore the concept of a gradient of a curve.

The first activity illustrates that the gradient of a function, at a point P, is the gradient...

This resource is an interactive excel program to enable students to investigate the solution of polynomial equations up to cubics using a graphical method.

The program shows the graphs of cubic equations and the...

This program allows students to solve pairs of equations by drawing 2 graphs and looking at the points of intersection. The graphs can be cubic, quadratic or linear. The 1st interactive sheet allows students to plot pairs of graphs by changing the coefficients of y=ax...

This resource is an interactive excel program to enable students to investigate exponential growth and decay. The topics of the interactive sheets are depreciation, exponential growth of bacteria and half life and radioactive decay.

This is a series of interactive excel sheets that look at histograms.

The first sheet contains a histogram displaying a summary of time spent travelling to work. A new set of data can be generated at the click of a...

This program begins with graphs of the hyperbola in the form x2/a...

This series of interactive excel sheets investigate models involving an inclined plane.

The first sheet helps students to investigate the conditions for movement of an object on a horizontal plane.

...

This series of excel sheets look at the area of regions bounded by linear and quadratic graphs.

The first interactive sheet calculates the area under the line y = mx + c between limits A and B. The effect on the area...

In this DfE Standards Unit resource, students interpret linear and non-linear distance-time graphs using the computer programme Traffic. This program provides a simple yet powerful way of helping learners to visualise distance–time graphs from first principles. The program generates situations involving...

Inverse Functions. Linear
This file starts with an example of how to find the inverse of a linear function. New examples can be generated and the graphs of both functions...

In this lesson students examine whether reports of extreme cold weather provide evidence that global warming is not happening. They look at the New York Times graphs of summer temperature distributions for the northern hemisphere for different periods and interrogate/critique these graphs.

Students will read...
