Geometry Everywhere

Betty R. Allen
Hughes High School, Hughes, Arkansas

Subject: Mathematics
Grade: 10

"With this activity comes a certain sharing of ideas that is not usually found in math problem-solving settings."

Purpose and Description of Project

The intent of Betty Allen's enrichment activity was to make students more aware of geometric shapes and lines in objects around them.

Activities

Students were divided into five groups-four to photograph geometric shapes and concepts at home, on the farm, in town, and at the lake, and one to label the resulting photographs and assemble them in four scrapbooks. After Allen's initial introduction, the groups met and planned their after-school visits to the assigned sites; then they visited the sites and, when they observed geometric forms, photographed them from more than one angle. Each group shot 24 to 36 photos which were commercially developed. When the photos were finished, the groups met during class to identify, without teacher assistance, the shapes in each picture. "The scrapbook committee assembled the materials, labeled the photos, and laid out attractive pages highlighting the shapes." Students were evaluated on the quality of their participation.

Materials, Resources, and Expenses

The students' primary resources were their eyes and imaginations. They used four 35 mm cameras, six rolls of film, four loose-leaf scrapbooks with adhesive-backed pages and clear plastic overlays, two packages of extra pages, and six packages of decorative stickers. The photos were commercially developed.

Outcomes and Adaptability

"The creative, inquisitive nature of the average and below average student came out to an unsuspected degree," notes Allen. They relished looking at their finished photos to see how well they had captured what they thought they had seen. Also interesting was the degree of carryover to visual analysis in problem solving. Allen found that the students were interested from beginning to end and that they planned well and carried out their plans promptly. As they talked about what they might find and, later, what they did find, the photos seemed to humanize geometry. As an added benefit, the resulting scrapbooks became a useful resource to use with future classes.

Allen suggests that this math activity could be adapted to any locality or class size. In addition to the topics here, geometry in transportation could be added or substituted. Because the three- to five-week project would take little class time, it could easily be worked into the regular curriculum at certain times of the year. Weather would be a definite factor if most of the pictures were to be taken outside as was the case with this project.
