- Students will need rulers, protractors, pencils, and paper.
- They can choose to add more wings, but the revolving door needs to have at least six in it.
- Here are the specifics of the assignment:
- Design a revolving door with at least six wings.
- Each angle must be congruent.
- Label each angle measure using a protractor.
- Identify line segments that are bisected.
- Identify the midpoint of each line segment.
- Label each part of the revolving door and demonstrate congruency.
III.MeetingObjectives
- Students will demonstrate an understanding of line segments, angles, congruency and bisecting angles in this
lesson. - Students will also demonstrate measuring angles and identifying angles.
IV.NotesonAssessment
- Assess student work by thinking about each of the following points.
- Were the students successful in executing a design that matches the specifics of the assignment?
- Are the angles of the wings congruent?
- Are the angle measures labeled?
- Is it clear that students understand the concepts discussed in the lesson?
Angle Pairs
I.SectionObjectives
- Understand and identify complementary angles.
- Understand and identify supplementary angles.
- Understand and utilize the Linear Pair Postulate.
- Understand and identify vertical angles.
II.ProblemSolvingActivity-VisualizeIt
- Students are going to go on a search for different types of angle pairs. This can be done in the classroom, but
it would be best to expand it to the entire school or outside. - If possible, allow the use of digital cameras.
- If this is not possible, students can draw sketches of the places where they locate each type of angle pairs.
- Students can photograph or draw each.
- They will need rulers, pencils, chart paper, clip boards.
- Students need to locate three examples of each.
- They first find three examples of complementary angles.
- Three examples of supplementary angles.
- Three examples of vertical angles.
- Students must write a description of each example and explain why it is a complementary angle pair, supple-
mentary angle pair or vertical angle pair. - Print student pictures and create a display of student work.
