The reduction mill reduces the thickness of a strip of steel using a series of rollers, each roller making the steel slightly thinner. The percentage reduction is constant on each pair of rollers. The mathematics used to calculate the actual reduction is similar to that used when calculating compound interest....

This SMILE resource contains two packs of games, investigations, worksheets and practical activities supporting the teaching and learning of reflection, from investigating folding symmetry to using matrices to perform reflections.

This resource from CensusAtSchool uses the ideas of estimating probabilities through finding the relative frequency of given data about favourite subjects at school. It uses sampling from different populations and investigates the effect of sample size on the estimated probability.

This collection from The Royal Statistical Society Centre for Statistical Education (RSSCSE) has been written to help make statistics lessons more relevant and engaging to teachers and students.

Having run the well known CensusAtSchool Project for the last eight years the RSSCSE are well aware of the impact...

Telemedicine is a new and fast developing field in healthcare. Even 20 years ago the idea of a surgeon being able to operate a robot from hundreds of miles away in order to perform an operation seemed like science fiction. Today, this is not only possible but engineers, working with scientists and doctors, are now...

The purpose of the Science, Technology, Engineering and Mathematics (STEM) Mapping Review, published by the Department for Education in 2004, was broadly to:

• investigate whether STEM initiatives currently being taken forward address the concerns raised about the decline in demand of university places in...

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...

Produced by the Learning and Skills Improvement Service (LSIS), these resources are aimed at mathematics practitioners. Sessions in this resource look at:

• Data collection and handling (using technology creatively and appropriately)

• Key features of charts graphs and diagrams (building on knowledge...

This lesson develops the concept of combining transformations. In particular students will:

• Recognise and visualise transformations of 2D shapes
• Translate, reflect and rotate shapes, and combine these transformations
• Discuss some common misconceptions about transformations
...

This is a problem solving lesson where students develop their understanding of how to interpret frequency graphs that use grouped data, together with their associated box plots. Particular attention is paid to minimum and maximum values, medians and quartiles.

The lesson begins with students interpreting...

This lesson develops the concept of using diagrammatic representations of calculations. Attention is paid to order of operations, along with the distributive and commutative properties.

An introductory activity considers areas of rectangles in relation to calculations, what is often termed ‘the grid method...

This is a concept development lesson that involves deepening understanding of how to calculate the mean, median, mode, and range from a frequency chart. Coverage is also given to using a frequency chart to describe a possible data set given information on the mean, median, mode and range.

The situation is...

This problem solving resource is intended to help students with recognizing and using proportional relationships, including through the use of graphs

Students are given information about a road race. They are presented with a map and information about the speeds of two runners. The race consists of four laps...
