### Corner to Corner

In this Nuffield activity students investigate how different numbers of squares can be joined corner to corner and the effect their arrangement has on the area of the rectangle that encloses the squares.

The key processes developed in this activity are:

*Representing - determining which aspects to...

### Co-primes

In this Nuffield investigation these resources from AMP, co-funded by the Clothworkers and Nuffield Foundation, students investigate how many positive integers are less than and co-prime to any given positive integer. This activity requires some confidence with the co-prime property, division and divisibility tests...

### Containers

This Cre8ate maths activity requires students to calculate areas of polygons and to appreciate the link with volumes of prisms. It may also involve detailed exploration of similarity.

### Comparing Datasets

This activity is produced by the Maths Magic project. Comparing Datasets provides examples and ideas for comparing data using mean, mode median, interquartile range and standard deviation. The examples suggested are: *Do males have faster reaction times than females? *Is life expectancy higher in the North or South...

### Colouring Maps

This activity from Subtangent is based on the four colour theory, which is used by mapmakers. There is an interactive task which challenges students to colour a map using no more than four colours and ensuring that no two regions which share a border have the same colour. Further resources include examples of...

### Coil Feed Line

This problem features a coil of tinplate being stored on a mandrel. In the first problem, students are presented with the diameter of the mandrel, the height from the floor, the width of the coil and the density of the steel. The problem is to calculate the maximum coil weight. A worked solution is included with...

### Classroom Olympics

These Cre8ate maths activities require the use of averages, ranges, percentages, histograms, stem and leaf displays, pie charts, and tables to make comparisons, interpretations, and conclusions. They also provide real data about pupils for analysis. Performing the “How far can you …?” events in the classroom will...

### Circles with Whole Number Points

Produced by the Maths Magic project, Circles with Whole Number Points provides teacher inspiration for investigating equations of a circle and Pythagoras’ theorem. The student task sheet refers to the use of Geogebra. The task consists of drawing circle, centre (0,0), radius 5 and finding all the points with...

### Chromatography of Leaves

In this classic experiment, from the Royal Society of chemistry, students use propanone to separate the pigments in a leaf. Chopping up the leaves, and grinding them up with propanone releases the pigments. Propanone is also the solvent used to separate the pigments. The resource is set out as teachers' notes...

### Chlorophyll fluorescence

From Solar Spark, this activity allows students to see how chlorophyll can be energised and how this causes it to fluoresce. Chlorophyll in plant leaves absorb red light and pass the energy on to other parts of the plant, hence leaves look green. But if there is nowhere for the energy to go, it gets released as...
