Introduction
We have been learning about different geometric shapes this past week. Today, I am going to introduce you to a circle. A circle is a round geometric shape that can be found in the real world.
Essential Questions:
How can I find the area of Geometric shapes?
Can I use Geometry in the real world?
Project Duration: 1 class period
(Presentation due tomorrow)
.
Task
In groups of two you will be researching different definitions of a circle. As you navigate through the links provided, you should also be able to define the different parts of a circle including it's radius, diameter, and circumference. You will need this information in order to find the area of the circle. I have also provided links to real world examples.
After you have completed your research you will be drawing life size examples of circles you have found in the real world. These will be presented to the class with actual measurements and area.
Process
The following links have been provided for your research:
1. Circle

2. Radius, diameter, and circumference
3. How to find the radius, diameter, circumference and area of circles?

5. Examples of Circles in the real world
6. Circles in the Real World

In order to complete this task your job is to provide in writing:
1. Your definition of a circle and it's radius.
2. The definition of the diameter and the circumference of a circle with formulas included.
3. The formula for finding the area of a circle.
For your presentation you will need to provide:
1. Two life size examples of circles from your research or experiences. (These should be drawn, colored, and cut out using poster board, paper, etc,)
2. Real measurements of your examples in inches or feet.
3. The real area of your object also in inches or feet.
*Note: Each student is to present one example and provide their own sheet with definitions and formulas
