THE SIX STEPS OF THE TASK
- Search three different circular objects that have also different sizes in or around your home.
2. Find the center of the each circular object with compass and straightedge or ruler on a paper.
è Decide whether objects are really circles or not. If they are not, search till find circles. If they are, draw them in your poster, name and paint them.
è Show your all works on the poster.
You start to prepare your poster in second step!
3. Measure and state the radius of the each circle.
Measure and state the diameter of the each circle.
4. Now estimate the circumference of three circles without using formula. State on your poster how to do the estimation and learn about Pi
-> Create a table that includes name of objects, radius of circles, and your estimate of the circumference (in cm)
-> Is there any pattern that you observe from the table? What could be the general formula including Pi?

5. You will also estimate the area of each three circle without using formula.
->Create a second table that includes name of objects, radius of circles, and your estimate of the area. ( in cm^2)
-> Is there any pattern that you observe from the table? What could be the general formula including Pi?
->Create a second table that includes name of objects, radius of circles, and your estimate of the area. ( in cm^2)
-> Is there any pattern that you observe from the table? What could be the general formula including Pi?
6. Write on the poster about what you learned when you work on this project ( Reflection ).
