This sub-collection of resources from the Virtual Text Book collection contains seventeen resources designed for use on an interactive whiteboard to aid the teaching and learning of a variety of topics in ‘Algebra: Using Equations and Functions’. Each resource is an interactive Excel worksheet to encourage teacher-...

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...

Produced by the Learning and Skills Improvement Service (LSIS), these resources are aimed at mathematics practitioners.

In this resource, sessions look at:

• Algebraic expressions (exposing and discussing common misconceptions)
• Multiplying out brackets (using rich collaborative tasks)...

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 SMILE resource contains three packs of games, investigations, worksheets and practical activities supporting the teaching and learning of algebraic structure, from forming simple formulae to changing the subject of a formula.

Algebraic structure pack one contains nine work cards with a...

Abstraction is the representation of essential features without including unnecessary details.  It is used to reduce the complexity of systems for users, hiding how things actually work, applying algorithms to different contexts and producing suitable user interfaces.  The first video explains the concept at a...

Alice and Bob in Wonderland are animations produced by the Perimeter Institute for Theoretical Physics. They are based around the questions that Alice has about the physical world and how these can lead to "powerful ideas" in physics, such as energy-mass equivalence and relativity. Topics include time travel, the...

Alien Invasion is a set of four interactive lessons about a full-scale alien attack that coincides with a class visit to Manford City. To set the scene and support the lessons, live television news bulletins, radio broadcasts and telephone messages help to develop the story line. The invasion leads to a series of...

Produced by the Royal Observatory Greenwich, this booklet gives instructions on a practical demonstration of the Doppler effect. The practical uses a portable speaker an audio software to calculate the change in frequency. Included is an online video that shows the demonstration and places it in the context of...

This podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection looks at invasive species of plants and animals. Many of them are well-known. Grey squirrels, harlequin ladybirds, buddleia, Japanese knotweed - the list goes on. Some of these aliens, or invasive species to give them...

Alison Foster has combined her education in Chemistry with her love of plants to engage in some exciting projects at the University of Oxford Botanic Gardens. This Catalyst article gives a profile of her career choices, and introduces a public engagement activity called Chemistry in the Garden.
