Geometry, Teacher\'s Edition

(Axel Boer) #1

  • Ask students to use the Wikipedia image of the National Mall to create a map of it.

  • This is Figure 10.03.01

  • http://www.en.wikipedia.org/wiki/National_Mall

  • Then tell the students that the mall is 1.9 miles× 1 .2 miles.

  • They are going to use what they have learned about scale and measurement to create their own map of the
    mall.

  • They need to choose a scale to work with.

  • Then they use grid paper to design the mall.

  • When students have the area of the mall correct, they can draw in as many different museums and monuments
    as they can.

  • Extra details add extra credit to their work.

  • When finished, allow time for students to share their work.


III.TechnologyIntegration



  • Use the following website on the National Mall in Washington DC.

  • http://www.en.wikipedia.org/wiki/National_Mall

  • Have students complete some research about the mall.

  • Possible questions include:

  • Who designed it?

  • When was it built?

  • What is at the North end?

  • What is at the South end?

  • How many different museums can you visit there?

  • Have you been to the mall?

  • Which museum would you most like to visit or did you enjoy and why?


IV.NotesonAssessment



  • Assess each student map.

  • Is the use of scale done correctly?

  • Are the measurements correct?

  • Is the map accurate?

  • Has the student take the time to add in details?

  • Provide students with feedback on their work.


Circumference and Arc Length


I.SectionObjectives



  • Understand the basic idea of a limit.

  • Calculate the circumference of a circle.

  • Calculate the length of an arc of a circle.


II.Cross-curricular-ThePantheon



  • Have students use the image of the floor plan of the rotunda of the Pantheon to calculate the circumference of
    it.

  • This is Figure 10.04.01
