- For example, this red and blue quilt square is made up of triangles that can be proven congruent using the SSS
Postulate. - Then the student would include measurements.
- Students can create this as a poster on poster board or using cloth and sewing by hand.
- If sewing, students could have a small quilt by the time they have finished this chapter.
- If working on poster board, they will have a poster when finished.
III.TechnologyIntegration
- Have students search on quilt making.
- There they can find directions on making quilt squares as well as different stitches to use.
- Students can also see examples of different quilts and quilt squares on different websites.
IV.NotesonAssessment
- Assess the student’s quilt square.
- Does it represent the SSS postulate?
- Is it clearly explained on the note card?
- Provide students with feedback as needed.
Triangle Congruence Using ASA and AAS
I.SectionObjectives
- Understand and apply the ASA Congruence Postulate.
- Understand and apply the AAS Congruence Postulate.
- Understand and practice two- column proofs.
- Understand and practice flow proofs.
II.Cross-curricular-Quiltmaking
- In this lesson, students are going to add on to their quilts.
- They need to design two different squares.
- One is going to use triangles that can be proven congruent using the ASA Congruence Postulate.
- One is going to use triangles that can be proven congruent using the AAS Congruence Postulate.
- Students need to create a color card with these two squares as well.
- They need to include measurements and explain how the triangles are proven congruent using the different
postulates. - This can be done as an addition to the poster that was started in the last lesson.
- It can also be done as an addition to a sewn quilt.
III.TechnologyIntegration
- Have students complete some research on the history of quilt making.
- Request that each student write a short report on its history and relevance in American society.
- Students can research their material at home or school and write the report as part of a final grade on the quilt.
