An MEI interactive demonstration of matrix transformations, which shows how a quadrilateral can be enlarged, reflected, translated, stretched or sheared and the corresponding matrix and image is displayed.

This engineering resource, produced by Mathematics in Education and Industry (MEI) for the Royal Academy of Engineering, asks the question: how can a camera, mounted on a helicopter, be used to track the location of a ground-based object? A number of discussion ideas are considered before using 2D and 3D...

This excel file contains a series of sheets which generate different types of equations involving algebraic fractions. The different types include denominators which are single term, linear and quadratic expressions. The quadratic expressions all have 1 as the...

This excel file contains a series of sheets which generate terms involving algebraic fractions which need to be combined and simplified. The different types include denominators which are single term, linear and quadratic expressions.

This interactive file shows how cubic polynomials can be divided by linear factors. The first four interactive sheets generate cubic expressions and the steps in the algebraic long division method can be gradually revealed. The constant term in the cubic can be altered...

This series of interactive excel sheets look at arithmetic series and progressions.

The first sheet gives examples of arithmetic sequences, of which the value of a further term in the sequence, the first term and the...

In this activity the goal is for students to understand how the regression line is chosen. Autograph has a built-in facility for showing the squares of the residuals and is required to make this task work. Students are asked to explore what the lines that give the sum of the y-on-x residuals equal to zero have in...

In this Core Maths resource students are asked to evaluate the offers and figures from three banks in order to decide which one is best for their company to borrow from. The resource involves students calculating the interest incurred using an Excel spreadsheet.

This excel program contains two interactive spreadsheets designed to explore the gradient functions of cubic and quadratic functions.

The first activity enables students to alter the coefficients in the function ax2+...

This Excel file has a series of sheets which illustrate the link between the equation of a circle and the corresponding graph. It goes on to deal with the intersection of a circle with a straight line.

The first...

This excel program contains a series of interactive spreadsheets related to the equation of the circle. The first sheets enable the student to alter the radius and centre of the circles centred at the origin and elsewhere. The program allows the student to view the...

This series of interactive excel sheets investigate models involving collisions.

The first sheet simulates two particles colliding. Initial velocity, mass and resulting velocity of the two particles can be set, or a...

This excel workbook contains a series of sheets to help students explore different types of composite functions including linear, quadratic and reciprocal functions.

The first sheet allows students to input different...

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...
