6-8
Using a circle that has been divided into congruent sectors, students will discover the area formula by using their knowledge of parallelograms. Students will then calculate the area of various flat circular objects that they have brought to school. Finally, students will investigate various strategies for estimating the area of circles.
6-8
Students measure the circumference and diameter of circular objects. They calculate the ratio of circumference to diameter for each object in an attempt to identify the value of pi and the circumference formula.

In this lesson students explore the concept of orbits, focusing on
altitude, velocity, and distance traveled. The lesson explores the
connection of Earth-orbiting satellites to the study of the
environment. Both geometric and algebraic concepts are presented to
students in this application of science and mathematics to a real-world
situation.
