The different types of quadrilateral are illustrated in the first seven interactive sheets of this excel file. Examples of each type of quadrilateral are shown and then further examples illustrated on a coordinate grid. The next sheet is more like a quiz as...

This collection of interactive excel sheets look at radians, arc length, sector area, converting to and from degrees, and other related problems.

The first sheet displays a sector of a circle and corresponding...

The rainforest interactive resource is provided by ASE and it includes images and information that is presented in text and symbol supported versions. The other resources provide ideas and examples on how you could be using symbols in your teaching to clarify meaning and understanding. The rainforest website can be...

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop ideas relating to the factors which affect the rate of dissolving and the particle...

These downloadable animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop ideas relating to the factors which affect the rate of evaporation and the particle model...

The simulation can be used to:

*Relate the real-world example of making sandwiches to chemical reactions.

*Describe what limiting reactant means using examples of sandwiches and chemicals at a particle level.

*Identify the limiting reactant in a chemical reaction.

*Explain the Law of...

This interactive file shows the graphs of functions and the graph of the corresponding reciprocal function. It begins with the graph of a linear function where the gradient and intercept can be changed. The reciprocal is plotted on the same diagram. The next two sheets...

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to introduce and explain the phenomenon of dissolving.

Dissolving is recognised by the formation of a clear mixture. Before mixing,...

This activity provides the opportunity for students to appreciate how mathematics plays a part in everyday life. The town council has allocated £100,000 to spend on reducing the number of deaths and serious injuries due to road accidents. Students are expected to adopt the role of planners who work in small teams...

This is a series of interactive excel sheets exploring linear regression.

The first sheet plots a scatter diagram and line of best fit for a small set of bivariate data. The mean and product moment correlation...

In this resource from the DfE Standards Unit, students interpret 2D representations of 3D shapes, analyse 3D shapes using plans, elevations, and isometric drawings and develop their reasoning ability in spatial contexts. Many students may have met these ideas before, but they may still experience difficulties in...

This simulation looks at resistance in a wire. Students can change the resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of a wire as the variables are changed.

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 resource contains two interactive excel files which deal with rounding of discrete and continuous variables and pose problems involving practical examples of calculations using rounded values.

Rounded Numbers: Bounds The first interactive sheet shows two numbers rounded to the nearest...
