This performance task is to be used as a culmination project after students have learned how to calculate surface area and volume of three dimensional solids. They should also have knowledge of nets of geometric solids and prisms, including how to create them and construct the solid from them. This satisfies many of the common core mathematics standards for geometry and measurement.
Students are being hired by the world famous chocolate company "Chocolat du Monde" to help decide on the most cost-efficient package to ship their mint truffles. After designing four their own nets of possible chocolate boxes, students will measure and calculate the cost of each box using the company's golden cardboard. They will then calculate how many of each box it will take to make the large shipment, and therefore calculate the entire cost of packaging. After making these calculations for four different possible boxes, they will write a formal recommendation to the company about which box would be best for them to use.
Note: This is designed for the students to create their own nets, but it could easily be adapted so that the students are given the nets. You could design your own or use some of the many that are available for free online.
