- Identify the exterior angles of convex polygons.
- Find the sums of exterior angles in convex polygons.
II.MultipleIntelligences
- Each of the examples in this lesson can be used as an extension to include multiple intelligences as you teach
this lesson. - I recommend not using the text with the students but teaching this lesson as an exploration.
- Have students work with rulers, protractors, paper and pencils at their desks in small groups.
- Have students work in pairs and/or groups of three.
- Then, present each section of the lesson.
- Have the students explore each example in their seats.
- For example, you draw the diagram on the board or overhead. Present a leading question, and then ask the
students to work with the figure to solve the dilemma. - When finished, allow time for class discussion.
- After going through each example in the text. Provide students with the notes for the lesson. They will have
an experiential understanding of the information through working with each example. - Intelligences- linguistic, logical- mathematical, visual- spatial, interpersonal, intrapersonal.
III.SpecialNeeds/Modifications
- Write all vocabulary and terms on the board/overhead.
- Define exterior angles.
- Formed by extending the side of a polygon.
- Two possible exterior angles for any given vertex.
- Define supplementary angles.
- Define vertical angles.
- Exterior Angle Sum
IV.AlternativeAssessment
- Alternative Assessment is done through observation of student group work.
- Use an observation checklist to be sure that the groups are working to discover the big ideas of this lesson.
