MP3 Players

In this Study Plus unit from the National Strategies students investigate buying and using an MP3 player. They consider best buys and compare different MP3 players, using proportional reasoning.

The unit looks at scatter graphs, ratio and proportion, percentage changes, and simple functions arising from real-life problems. The pupils would benefit from access to ICT and if possible the Internet to research prices and data about MP3 players. If the Internet is not available, a range of shopping catalogues will provide the same information.
