- Students will calculate the area of a circle.
- Students will use area in problem solving.
IV.NotesonAssessment
- Be sure that each of the pieces of the solution is in the student’s answer.
- Offer correction/feedback when necessary.
Regular Polygons
I.SectionObjectives
- Recognize and use the terms involved in developing formulas for regular polygons.
- Calculate the area and perimeter of a regular polygon.
- Relate area and perimeter formulas for regular polygons to the limit process in prior lessons.
II.ProblemSolvingActivity-TeachingTime
- In this activity, students are going to teach the other students in the class.
- Divide students into small groups.
- Assign each group one of the following.
- Explain what makes a polygon a regular polygon
- Parts and terms of a regular polygon
- Figuring Perimeter- one group getsP=ns
- Figuring Perimeter- one group getsP= 2 nx
- Calculating Area usingA=^12 Pa
- Once each group is given their assignment, their work is to demonstrate/teach their topic to the other students.
- Each group needs to use a diagram.
- Each group needs to have an example that demonstrates.
- Each group needs to have an example for the rest of the class to work with.
- Allow time for students to work and then present their topics.
III.MeetingObjectives
- Students will recognize and use the terms involved in developing formulas for regular polygons.
- Students will calculate the area and perimeter of a regular polygon.
- Students will demonstrate understanding by teaching this material to their peers.
IV.NotesonAssessment
- Take notes on each group’s presentation.
- Is the material clearly presented?
- Have the students successfully used a diagram?
- Are the students able to answer questions from others in the class?
- Offer correction/feedback as needed.
