### Finding the Golden Ratio in Durham Cathedral

This video resource from Teachers TV is presented by Steve Humble. Filmed in Durham Cathedral, it investigates the mathematics used by master masons and the links with classical architecture. Steve investigates the proportions in Durham Cathedral and discovers ratios that are very similar to the golden ratio....

### Shopping Mall

This video resource from Teachers TV is presented by mathematics adviser and performer Isaac Anoom. Filmed in a shopping mall, it raises quick-fire starter questions on: surface area of an octagon, calculating percentages, determining the best buy, probability, ordering fractions using reciprocals...

### Ratios and Proportions

This video resource from Teachers TV is presented by Fran and Dave, who demonstrate a practical application of ratio and proportion as they prepare for a dinner party.

The number of guests requires the adaptation of recipes for both food and drink. Graphics are used effectively throughout the video to...

### Working with Formulae

This video resource from Teachers TV is presented by Fran and Dave, who use the length of a runway at an airport to demonstrate a practical application of mathematics. Graphics are used to demonstrate how to rearrange a formula.

Measurements, taken at an airport, are substituted into relevant formulae to...
