This Core Maths activity investigates diamond smuggling.

The presentation gives details of how diamonds were smuggled out of Namibia in cans of pilchards. Students need to use the information given to calculate an estimate of the value of the smuggled diamonds. They need to use estimation and the formula for the volume of a cylinder. The last two slides provide a scaffold for the task with detailed answers.  A more open ended approach to the task can be presented to students by omitting those two slides. 

The teachers' notes give a brief outline of the task with ideas for extensions. The possible extension activities require access to the internet.
