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 read...

This interactive simulation gives the opportunity for students to explore Least-Squares Regression. There are a number of different options available from the drop-down menu or students can plot their own points. Students then use the sliders to add their own line of best fit, residual lines and squared residuals...

In this activity students make a comparison of conventional and energy saving light bulbs and ask the questions: How can individuals contribute towards the needs of society? Why have traditional light bulbs been abolished by the EU? In Germany, as in many other European countries, conventional light bulbs are to be...

This resource is an interactive excel program to enable students to solve some different types of linear equations. Each interactive sheet begins with an example of how the student could write out each stage of the solution. Students can click on the cells which are...

This interactive excel file allows students to investigate loci. Each of the interactive sheets enables students to see random points on or near the locus and how the locus is constructed. Loci include the locus of points equidistant from a point, from a line segment...

This MEI resource for complex numbers demonstrates loci in the Argand diagram. In the complex plane the horizontal axis are real numbers and on the vertical axis are imaginary numbers.

The excel file uses sliders to alter the position of the point on the plane. The point can be picked up and moved into all...

This resource looks...

This series of interactive excel sheets aimed at Key Stage Two students explores long multiplication. Answers can be checked each time and new questions generated at the click of a button.

The first three sheets look...

This series of excel sheets look at the turning points of quadratic and cubic functions. New examples can be generated on each sheet every time the resource is used.

The first interactive sheet shows the gradient at...

In this activity students adopt the role of a small team of undercover environmentalists, deep in a tropical rainforest, on a mission to investigate and expose the illegal activities being carried out by a multinational logging organisation that is destroying the planet.

Rainforest involves four lessons:...

This excel file looks at using the sine curve to model the water depth in a tidal river.

The first interactive sheet shows how the Earth’s orbit around the Sun can be modelled by the sine curve. One or two cycles can...

This interactive program deals with the modulus function applied to linear, quadratic, reciprocal and sine functions. The graph of each function is shown as well as the unreflected sections of the graphs.

The first...

This series of interactive excel sheets investigate models involving moments.

The first sheet helps students to investigate the moment of a force about a point. The components of the force can also be revealed.

This resource, aimed at early years and lower primary, contains an interactive spread sheet designed to illustrate teaching points on the topics of money. Ideal for use with the whole class at the start or end of a lesson it provides screens on the following:

This resource contains two interactive excel files dealing with aspects of multiplication of integers and decimals.

Long Multiplication...
