- Then have the students do a search and choose a pyramid.
- Students are going to use the dimensions of this pyramid to build a model.
IV.NotesonAssessment
- Assess student work through discussion and observation.
- Do the students understand who Thales was and the significance of his discovery?
- Is the student model to scale?
- Were the students able to come up with a way to test Thales’ findings?
- What are students sharing about this assignment?
- Is higher level thinking involved?
- Provide students with feedback as needed.
Similarity by SSS and SAS
I.SectionObjectives
- Use SSS and SAS to determine whether triangles are similar.
- Apply SSS and SAS to solve problems about similar triangles.
II.Cross-curricular-Literature/Poetry
- In this activity, students need to create a poem, song or story that explains the three ways to figure out if two
triangles are similar. - The first is AA- angle angle
- The second is side- side- side.
- The third is side- angle- side.
- You can begin this lesson by reviewing the definitions of each and how to use them to figure out if two triangles
are similar. - Then divide students into groups of three.
- Have the groups work on their expression of figuring out if two triangles are similar.
- When finished, allow time for the students to share their work.
III.TechnologyIntegration
- Students can go to the following class zone website and see the animation on similar triangles.
- http://www.classzone.com/cz/books/geometry_2007_na/get_chapter_group.htm?cin=2&rg=animated_math&at=animations&var=animations
- This is a fun interactive way to see the work done.
- Because class zone is affiliated with another textbook, the students can have a difficult time navigating the
site. - Use the link above for it.
- This will bring the students to the animation.
- If you don’t wish to use class zone, students can also go to futureschannel.com and see a short movie on
triangles and architecture.
IV.NotesonAssessment
- Assess each group’s poem or story.
- Does it explain how to figure out if triangles are similar?
- Is each theorem well explained?
- Provide students with feedback as needed.
