In previous math courses, students were introduced to perimeter and area of polygons and circles.  Unit 7 reviews and expands on these concepts by allowing students to calculate the area and perimeter using different formulas.  They will find the measurement of parts of a circle they have not been introduced to yet.  It will also introduce them to the ideas of inscribed and circumscribed polygons.  Finally arcs, tangents, and other parts of circles are explored and the relationships of these parts to each other.

 This unit should take approximately 5 - 6 weeks.
