This lesson unit is intended to help teachers assess how well students are able to: Select appropriate mathematical methods to use for an unstructured problem; interpret a problem situation, identifying constraints and variables, and specify assumptions; work with 2- and 3-dimensional shapes to solve a problem involving capacity and surface area; and communicate their reasoning clearly.

Students represent three-dimensional candy cartons using nets. They design a box to fit a given an upper limit (the total surface area must fit on a single sheet of paper) that will hold a given volume of candy. Students are required to draw either an accurate full sized or scale drawing net including flaps necessary for carton construction. After completing the task, students can analyze sample student work to deepen conceptual understanding.
