- Protractor Postulate
- Angle Addition Postulate
IV.AlternativeAssessment
- Use an observation checklist to observe students as they work.
- Pay attention to the questions asked during the lesson.
- Make a note of students who are having difficulty. Consider flexible grouping to assist these students in their
work.
Segments and Angles
I.SectionObjectives
- Understand and identify congruent line segments
- Identify the midpoint of line segments
- Identify the bisector of a line segment
- Understand and identify congruent angles
- Understand and apply the Angle Bisector Postulate
II.MultipleIntelligences
- We can differentiate this lesson by organizing the content into a table. This is done as part of a class discussion.
It is not done ahead of time and then presented. Creating the chart is meant to be interactive. Since this lesson
works with line segments and angles, we can use these as the two columns of our table. Here is a sample of a
table and how to organize it for the students.
TABLE4.1:
Line segment Angles
Congruent (show example) Congruent (show example)
Segment midpoint Show vertex and sides
Show symbols Show symbols
Segment midpoint postulate Angle bisector postulate- Be sure to explain each concept and how they are different and similar depending on whether you are working
with line segments or angles. - This helps the students to see the connections between the concepts.
II.MultipleIntelligences : Linguistic, logical- mathematical, spatial- visual, interpersonal, intrapersonal
III.SpecialNeeds/Modifications
- Review previously learned information. One way to do this is with students working in pairs to quiz each
other. - Write all vocabulary on the board/overhead. Request that students copy this information in their notebooks.
- Vocabulary
- Congruent with symbol
- Segment
