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.

The first interactive sheet shows a table of pairs of integers for students to reveal the factors and sets of multiples. The HCF and LCM can be revealed. New pairs of digits can be shown, either easy or more challenging. Each number is shown as the product of its prime...

In this resource the head of a circular snowman rolls around its circular body to make one trip back to where it started. The ratio of the diameters of the circles is given. The challenge is to find how many times the head will revolve throughout the journey, and find a general rule.

The resource contains a...

This activity challenges students to design, and agree on an optimal route for, a village bypass, subject to the Highways Agency constraints for road design. Students use the provided software or physical resources and measure lengths of lines and curves, fine tune cost-benefit trade-offs, interpret data, convert...

In this activity, students explore the miss-match between real and perceived risk by exploring the risks of dying unexpectedly from various causes. Starting from known fears and comparing them with real-life data, students can recognise that these fears are often unfounded. Students have the opportunity to learn...

In this activity students are asked to construct a simple mathematical model to help decide whether or not the umpire has made the correct decision. Students are required to revisit and test assumptions made in their initial model, make estimates of likely uncertainty and apply their model to similar situations....

This resource contains two interactive excel files providing an introduction to indices, dealing with products and quotients involving indices and evaluating fractional indices (positive and negative). Each file contains the same further 16 sheets of questions which may...

This resource contains two excel programs with interactive spreadsheets dealing with linear inequalities in one or two variables.

The first interactive sheet shows a calculator for Simple Interest where the amount invested, the rate of interest and the term can be altered. The next sheet shows sets of five questions on Simple Interest to be answered with the help of calculators. Answers can be...

This interactive excel file has separate sheets which deal with inverse proportion where the functions are linear, quadratic and square root. Each sheet begins with a statement of the proportional relationship and values so that the constant can be calculated and the...

In this activity students make a comparison of conventional and energy saving light bulbs and ask the questions: How can individuals contribute towards the needs of society? Why have traditional light bulbs been abolished by the EU? In Germany, as in many other European countries, conventional light bulbs are to be...

This resource is an interactive excel program to enable students to solve some different types of linear equations. Each interactive sheet begins with an example of how the student could write out each stage of the solution. Students can click on the cells which are...

This interactive excel file allows students to investigate loci. Each of the interactive sheets enables students to see random points on or near the locus and how the locus is constructed. Loci include the locus of points equidistant from a point, from a line segment...
