Geometry and Measurement of the World's Most Famous Structures
Subject Area:
Mathematics
Grade Level(s):
8
Duration of Activity:
23 days
Description of Activity:
This lesson is designed to create awareness in students about how geometry is used in the everyday world in which they live. The student will learn how to find and investigate Web sites for specific information. This lesson is designed to integrate social studies and technology into mathematics classrooms and to show students how to do research on the World Wide Web. The student will use the Web sites and links of wellknown structures to locate the answers to specific questions related to polygons and other geometric shapes of 3dimensional objects, measurement of the buildings, and formulas used to figure the dimensions of these structures. Students may work in pairs or in small, cooperative groups to answer Handout 1: Web Search for the World's Most Famous Structures.
Objectives:
The student will
 research selected sites on the World Wide Web.
 identify polygons and other geometric shapes.
 learn about threedimensional figures.
 develop an understanding about how measurement formulas are used in the world outside the classroom.
 compose a paragraph to demonstrate an understanding of geometric shapes and measurements.
Materials/Equipment:
 Computers
 Access to the World Wide Web
 Wordprocessing software
 Handout 1: Web Search for the World's Most Famous Structures
Prerequisites (skills or background needed):
 Basic knowledge of computers
 Basic knowledge of locating sites on the World Wide Web
 Understanding formulas used to show the measurement for area and volume of a geometric shape
 Knowledge of basic polygonal and other geometric shapes
Procedure
Teacher Component:
The teacher will
 tell the students that geometric shapes and mathematical formulas are used to find area and volume measures for buildings in the world outside the classroom.
 review polygons and other geometric shapes if necessary.
 tell the students to search and investigate the Web sites listed under the Student Activities section of this lesson to complete the answers on Handout 1: Web Search for the World's Most Famous Structures.
 instruct the students to select one of the structures visited in their Web searches and compose a paragraph demonstrating an understanding of how this structure is representative of the two and threedimensional geometric shapes, formulas, and mathematical measurements used in the world outside the classroom.
Student Activities:
The student will
 visit the Web sites (a) The Great Building Collection, http://www.greatbuildings.com and (b) The White House, http://www.whitehouse.gov/, and use the information found on these sites to answer the questions on Handout 1. Links to specific structures can be found using the following URLs:
 The student will select one of the structures and write a paragraph about to demonstrate an understanding of the two and threedimensional geometric shapes, formulas, and measurement in the real world.
Accommodations:

Students who experience difficulty completing the assignment will work with a peer helper to locate Web sites and to find information on the Web.
Extension Activities:
 The student will select one of the structures researched to create a scale model for a formal presentation to the class.
 The student will present a PowerPoint presentation on the geometric facts describing one of the structures researched on the Web as part of this lesson.
 Using Microsoft Access or other appropriate software, students will work in cooperative groups to create a database of information about the buildings researched in this lesson. They can list information such as the height of each structure, the year it was constructed, the city and country or city and state where each building is located. This database can be added to from year to year as other structures are researched, and the information in the database can be used to create math problems similar to those in this lesson.
 Using Microsoft Excel or other appropriate software, students will create a database of facts about buildings in their own community, listing information such as geometric shape, dimensions, and year constructed. This database can be added to from year to year and the information used to create math problems similar to the ones in this lesson.
