In this Nuffield resource rooms in a rectangular maze of rooms have bags with a varying number of gold coins. Students explore the effect of the route on the number of gold coins that can be collected.

The key processes involved in the activities are:

*Representing - identifying the mathematics...

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 interactive game from the Association for Science Education (ASE) tackling the interpretation of distance/time graphs in the context of a football match. Graph Shots is an interactive game that develops students' understanding of distance/time graphs. Students compare graphs with written accounts and video...

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...

Graphing Lines gives the opportunity for students to explore the parameters of a linear equation; how modifying the graph affects the equation and how modifying the equation affects the graph. Students can draw reference lines y=x and y=-x to help with their deliberations. Students may change the point of...

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.
