- 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
