Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade with classmates, who calculate surface area and volume of some of the structures. Refers to a Discovery Education video/DVD to support and enrich the project; a link takes you to a website to order it. Charts mentioned are not attached.
