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 simulation allows students to:

  • Demonstrate an understanding of acid and base strength, given acids or bases at the same concentration, by:
  1. Relating the strength of an acid or base to the extent to which it dissociates in water
  2. Identifying all...

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.

The fundamentals of programming are covered: • Arithmetic operations • Data types • Control flow As well as some more advanced techniciques including the use of: • Regular Expressions • Files •...

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...

Birmingham Institute for Forest Research (BIFoR) has provided a free online learning platform for schools which includes curriculum linked activities, developed to support secondary school students. These activities provide the opportunity for students to join a growing community of citizen scientists who are...

This simulation explores the Beer's Lambert Law. It allows you to make colourful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer.

Curriculum links include:

• Beer's law
• Solutions
• Concentration
• Molarity...

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.
