Research-based guidance and classroom activities for teachers of mathematics

Product wars

For this task, go to the Bowland Maths website and click on  Classroom projects - the Case Studies. Scroll down the list using the arrow at the bottom until you see a case study called Product Wars.

Students assume the role of apprentices in a soft drinks company and are invited to create the ultimate range of smoothies. Different mixtures with different tastes and nutritional values can be tested using market research. Spreadsheets are used as tools to keep track of varying taste and nutrition. Ratio of ingredients within each recipe can be recorded and compared, and scaling up for production or scaling down for testing purposes can be carried out.

As with many ratio and proportion tasks, it is possible to maintain an ad hoc approach and learners left to themselves may not make links to other ratio and proportion tasks and the underlying concepts.
