This resource from Susan Wall contains a number of open–ended questions which explore understanding and allow a variety of approaches.

Each question is easily accessible but can be extended to make a more complex problem. Students are required to justify their answer and, where possible, generalise their...

This set of  activities from OCR illustrate the concept of concurrency in algorithm development. A teacher pack and learning activity packs are provided. Activities move from the familiar, division of labour when washing up, to the less familiar topic of writing programs using threading in Python. Routing and...

Tin cans come in a variety of shapes and sizes. In this activity students consider the net of a tin can, the formula for the total surface area and the formula for the volume of the can. The first problem requires students to express the total surface area as a function of r by eliminating h. The second problem...

This mystery explores solubility, ionic ...

This Nuffield Working with Science unit aimed to excite interest in natural and built environment while encouraging students to take an interest in environmental issues.

This series of activities from NASA take a mathematical approach to looking at transits, eclipses and occultations. They are intended as supplementary problems for students looking for additional challenges in mathematics and physical science from age 11 to 19 years.

The problems were created to be authentic...

The cost of transportation is a key factor for many industries. This activity features a classic transportation problem giving the outputs of two suppliers, the demands of two consumers and the associated transportation costs. Students are asked to find the minimum transportation cost to meet the demand. Students...

This interactive excel program covers distance/time and velocity/time graphs.

The first interactive sheet shows a distance/time graph made of line segments and some questions relating to speed for each segment and the...

In this resource the side lengths of a triangle are given. The challenge is to find the ratio of the product of each of the tangents, divided by the sum of each of the tangents.

Each student worksheet contains a different triangle, but the answers all have something in common.

The solution involves...

This resource contains two interactive excel files dealing with the graphs of trigonometric functions.

Trigonometry: X=cos, Y=sin...

This resource contains twelve problems requiring students to explore the properties of the functions of sine, cosine and tangent. Students explain which is the odd one out, state which functions can be represented by which graph, devise questions which give a certain set of solutions and state whether statements...

Mathcentre provide these resources which cover aspects of trigonometry, often used in the field of engineering. They include the trigonometric ratios, using Pythagoras’ theorem and working with the sine and cosine rules.

Comprehensive notes, with clear descriptions, for each resource are provided, together...
