In this resource students are given the coordinates for each vertex of a triangle, with two of the vertices being horizontal. The challenge is to determine the ratio of the tangents of two of the angles.

Each student worksheet has a different triangle, but the solutions all have something in common.

In this activity students tackle the problem of assigning a level of difficulty of various texts and books. The reading age is about the level of difficulty of text rather than the reading competence of the reader. The resource comprises an overview, teacher guidance...

From the LSIS, these materials cover two sessions designed to take students through the basic principles of manipulating and solving equations. The learners work through building an equation, checking the equation and solving the equation. They are then asked to create their own equation and swap it with a partner...

The reduction mill reduces the thickness of a strip of steel using a series of rollers, each roller making the steel slightly thinner. The percentage reduction is constant on each pair of rollers. The mathematics used to calculate the actual reduction is similar to that used when calculating compound interest....

These activities cover bivariate data which includes regression and correlation.

[b]Least squares regression[/b] spreadsheet is designed to help students get a feel for drawing a line of best fit through a set of points and to begin to understand the concept of regression. Students are given a set of six...

Produced by the Learning and Skills Improvement Service (LSIS), these resources are aimed at mathematics practitioners. Sessions in this resource look at:

• Data collection and handling (using technology creatively and appropriately)

• Key features of charts graphs and diagrams (building on knowledge...

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 RISP activity, The answer's 1: what's the question?, gives students graphs containing shaded areas enclosed by two functions. Examples of a straight line and a quadratic graph, a cubic graph and an exponential graph are used. Given that the enclosed area has a value of one, students are asked...

Two Repeats covers the revision of algebraic topics including changing the subject of a formula, graphical solution of equations, solving simultaneous and quadratic equations and manipulating surds.

...

Two RISP activities designed for students to explore or consolidate ideas about integration.

Introducing e requires students to use a graphing package to explore a variety of functions of the form y...

This detailed exemplar explores the rocket engine performance in the BLOODHOUND SSC engineering project. It requires student knowledge of physics, chemistry and mathematics when applied in mechanical engineering.

The aim of the route inspection problem is to find a route that is as short as possible yet goes down every road once and returns to the starting point. The task informs students that there has been a heavy snowfall overnight and that the students are required to clear the roads in the town centre as quickly as...

In this activity from the Nuffield Foundation, students carry out an experiment to collect data about a trolley rolling down a slope. They then use this data to simulate the motion of a train by fitting a quadratic curve to their data, using a graphic calculator or spreadsheet. The slideshow provides an...

This resource is based on a Russian fable about deciding which girls from the village should be married. The aim of this resource is to allow students to meet a different type of problem involving listing of possible outcomes. Once outcomes are listed the probabilities...

STEM Activities with TI-Nspire is a series of booklets featuring activities that exploit the potential of the TI-Nspire in STEM contexts. All the activities contain some background scientific or other information together with links to appropriate websites. Many of the activities are suitable for a range of ages...
