- Another option is to have the students design their own A frame home.
- When designing, the students will have to use the concepts in the chapter and apply them to the design of the
home.
III.TechnologyIntegration-Websearch
- A great way to study the concept of bisection is through a websearch.
- Have the students google “bisecting”
- When they do this, many pages of images will pop up. For example, one image is of a fence bisecting two
mountains. Another is an aerial view of a highway. - Ask students to select three different real- world images to work with.
- You want the students to draw connections between the concepts in the text and the images that they have
selected. - Ask the students to investigate how the terms bisect, congruent and midpoint applies to each image.
- For example, the student might see that in the highway picture the roads are bisecting by other roads. In the
mountain picture, the fence crosses the midpoint between the two mountains bisecting the distance between
the two. - This activity will cause students to use higher level thinking skills. The connections may not be obvious.
IV.NotesonAssessment
- Look at student work.
- Are the students able to apply how each concept applies to the A frame home design?
- Look at student designs- is the A frame home congruent?
- Are the angles congruent?
- You could choose to do some or all of the suggestions in this lesson, you are looking to see that the students
understand the concepts and can apply them in real life situations. They could be doing this in a diagram, a
presentation or a written explanation. - Assess student work accordingly.
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
Cross-curricular-MapofNYC
- Use the image of a street map of Manhattan. This is Figure01.05.01.
- http://www.aaccessmaps.com/show/map/us/ny/manhattan
- Print a copy of this image for students to work with during the activity.
- This map has many different examples of complementary and supplementary angles. As well as vertical
angles. - Have the students work in pairs with a highlighter, colored pencils or markers.
- The students are going to identify examples of each of the types of angles in the map.
- Remind students to look at Broadway and at the way Broadway intersects the other streets.
