Review appropriate notation for angle measurement, and describe angles in terms of the amount of turn. Use reasoning to determine the measur es of angles in polygons based on the idea that there are 360 degrees in a complete turn. Learn about the relationships among angles within shapes, and generalize a formula for finding the sum of the angles in any n-gon. Use activities based on GeoLogo to explore the differences among interior, exterior, and central angles.
Explore the concept of the mean and how variation in data can be descr ibed relative to the mean. Concepts include fair and unfair allocation s, and how to measure variation about the mean.
Use dynamic geometry software to construct figures with given characte ristics, such as segments that are perpendicular, parallel, or of equa l length, and to examine the properties of parallel lines and circles. Look past formal definitions and discover the properties and relation ships among geometric figures for yourself.
Explore several methods for finding the volume of objects, using both standard cubic units and non-standard measures. Explore how volume for mulas for solid objects such as spheres, cylinders, and cones are deri ved and related.
Standing on the banks of the Delaware near Philadelphia, Dave recalls the victory at Trenton, New Jersey when the Continental Army crossed the Delaware and overcame the Hessian troops under the command of Colonel Rall. At Monmouth Battlefield State Park Dave introduces the "first Pentagon", a dining room at Ford House that served as meeting place for the leaders of the Continental Army in the two winters that Washington and his troops prepared for the final battles of the Revolutionary War.
The flapping of a butterfly's wings over Bermuda causes a rainstorm in Texas. Two sticks start side by side on the surface of a brook, only to follow divergent paths downstream. Both are examples of the phenome non of chaos, characterized by a widely sensitive dependence of the fu ture on slight changes in a system's initial conditions. This unit exp lores the mathematics of chaos, which involves the discovery of struct ure in what initially appears to be random, and imposes limits on pred ictability.
