From founding communications, such as the fire beacon, to being able to communicate with space, there is no denying that developments in communication have advanced at a rapid speed. This topic, from the Institution of Engineering and Technology (IET), presents students with communications of the past, present and...

A diagram is shown with a circle, centred on a rectangle with given dimensions.  Semi-circular arcs are drawn with the sides of the rectangle as diameters. The areas between the semi-circles and the circles form crescents. The task is to calculate the area of the crescents.

When working on the numerical...

This Catalyst article looks at hydraulic fracking, the process of breaking up rocks deep underground using high-pressure water mixed with sand and chemicals. The process has been used for decades in the energy industry to free oil and gas trapped in rock formations. However, questions have been raised over the...

This National Strategies Study Plus unit has been designed to cover a number of areas of mathematics, particularly work with number and algebra. It also addresses a range of learning styles along with links to literacy and ICT through the use of spreadsheets.

Using the topic of fractals, studnets explore...

This activity requires students to be able to add, subtract, multiply and divide fractions. Each letter of the alphabet is represented by a fraction. Students perform calculations, the answers to which are converted into code words. Questions are in three groups: addition and subtraction of fractions,...

This resource from Defence Dynamics help students to understand the process of fractional distillation in the context of crude oil distillation. In the first activity, students consider the physical properties of different oil fractions. They then compare their boiling ranges and examine the relationship between...

Fractions of X (mental arithmetic) This excel file has four interactive sheets. Each sheet shows sets of questions where students find the fraction of given amounts. Answers can be revealed and new sets of...

This resource contains seven instant maths ideas covering a whole range of suggestions that may be used as starter questions, extension questions or probing questions to assess understanding. Areas covered include: * drawing number lines to aid conversion between fractions, decimals and percentages * resources to...

In this activity, students have to use their knowledge of fractions, decimals and percentages in order to check whether the correct answers have been given. By checking the given answers and spotting errors, students identify who committed the crime, who the victim was and who were the other two suspects, where the...
