Have the students work on a research project about one particular area of geometry to strengthen interdisciplinary ties with verbal skills. Some examples of research topics include the history of geometry, the purpose of learning about geometry, the various types of polygons, geometric features of ancient sites or geometry in everyday objects. Require the students to conduct research online and in the library and to include proper citations in their research papers.
Divide the students into groups, or allow each student to work on his own scale model. Assign each student or group a different structure, such as a local bridge in town, the Empire State Building or the Eiffel Tower. Require the students to make a three-dimensional model out of clay, blocks or another medium of their choosing. The model must be to scale, and they must include a scale along with their model.
Have the students use what they have learned about geometry to complete a WebQuest by themselves or with others. WebQuests allow students to learn background information about a topic and then use it in a way that applies to real life. Some examples available at the Mathematics WebQuests site include "Using Area and Perimeter to Design a Fun House," "Quilting Our Way Through Geometry" and "What in the World is a Shape?"
Divide the students into groups for this project. Assign each group an different topic you either did not cover or only spent a little bit of time on during the year. Topic examples include finding the volume of a rectangular prism, perimeter of a square and surface area of a cube. Have the students read their textbooks and work with you so they can present the topic to the class and teach their classmates.
