1.  What do you know about circles. (All circles have a center, a radius, a diameter, a circumference, and an area.)

2.  What are some things you know about squares. (All squares have 4 equal sides, 4 right angles, a perimeter, and an area.)

3.  How do you calculate the circumference of a circle? What information is needed? (How about the diameter. Pi x D = C.)

4.  How do you calculate the perimeter of a square? What information is needed? (You need the measurement of one side. 4 x a side = P.)

5. Draw a diameter from left to right through the middle of the circle, parallel with the bottom of the square. Is the measurement of the diameter the same as the width of the square?

6. Imagine that the diameter of the circle is 7 meters. What is the circumference? (Use 22/7 for Pi.)

7. If the width of the square is the same, what is the perimeter of the square? Which is longer, the perimeter of the square, or the circumference of the circle?

8. Imagine that the diameter of the circle is 10 meters. What is the circumference? (Use 3.14 for Pi.)

9. If the width of the square is the same, what is the perimeter of the square? Which is longer, the perimeter of the square, or the circumference of the circle?

10. Imagine that the diameter of the circle is “D” meters. What is the circumference? (Use 3.14 for Pi.) (D x 3.14)

11. If the width of the square is the same, what is the perimeter of the square? Which is longer, the perimeter of the square, or the circumference of the circle? (D x 4)
