“Don't Fence Me In”
For Geometry ( 9th Grade Math )
E-Mail: [email protected]
Mrs. O McDonald had a fenceless farm E-I-E-I-O. The cows are wandering, will you please help her make them a home? She cares for her cows’ happiness. She wants to build the corral so that there is as much space as possible inside it for the cows to move around.
Your objective is to construct a corral for her
wandering cows. The corral that you construct
should contain the largest possible area of the
rectangle, the most room for the cows to move
around. You should find a formula or rule for
width and area of the rectangle later.
Please read this entire page before starting the activity.
List the differences between the definitions of perimeter and area on your spreadsheet
8.Choose the best corral for her cows.
This paragraph should include: The perimeter of the corral and the area of the corral
Why your corral is the best solution to the problem
To review the definitions of perimeter and area click on the link below.
1. Perimeter of Polygon
2. Area and Perimeter
Points Available 20
Points Earned 20
Students list the differences between area and perimeter.
Students complete scale drawings for each possible corral.
Students label each scale drawing correctly
Students identify all possible areas and perimeters of corral, which can be constructed. (Completion of In-Out Table)
Student's paragraph clearly state which corral they would build and why.
You and your partner did a wonderful job~! After working with your group project, you should be able to achieve and obtain following skills:
I hope you enjoyed your WebQuest.
The purpose of this WebQuest was designed to have students work in cooperative learning groups, using real-life situations and problem-solving skills to identify the differences between area and perimeter. It also shows you that rectangles can have the same perimeter, but they may have different areas. They can use a spreadsheet to organize and analyze the data from their group work. Students can reason through the process of gathering the data from individual from the group using technology(excel, math software like geo-sketchpad). They can visualize the geometry and can enhance understanding the concept. They will conclude from the data. I hope you enjoyed your
