Project Rubric

Opening

Project Rubric

Work with a partner to review the project rubric.

  • Take a few minutes to study the rubric by yourself.
  • Without looking at the rubric, take 1 minute to describe the rubric as completely as possible to your partner (who can look at the rubric). Your partner should listen carefully to your description.
  • Briefly look at the rubric again. Your partner should now take 30 seconds to add to your description of the rubric, without repeating any of your description and without looking at the rubric.

Project Work

Today you will use scale to determine measures of your buildings. You will use the scale 20:1—that is, 20 ft to 1 in.

Follow these steps for each of your model buildings. Keep the rubric in mind as you work on your project.

  • Decide on a height for the full-size building. (It should not be taller than 200 ft.)
  • Use the scale to calculate the height of your model building based on the height of the full-size building.
  • Measure the dimensions of the polygon base you made in the first project lesson.
  • Using the scale, calculate the dimensions of the base of the full-size building.
  • Determine the area of the base of the full-size building.
  • Draw a sketch to show what your model building will look like.

Hint:

  • As you work, use the project rubric to evaluate your progress and make sure you are on the right track.

Make Connections

Look at the rubric again.

  • Notice the blank column with the heading “Specific to This Project.” Is there anything that you think should be added to this column?
  • Next, look at the bottom row that is blank. Is there any scoring criterion for the project that you think should be added here?
  • Take a few minutes to discuss these questions with your partner. Write down any ideas you have.
  • Discuss your ideas as a class. As you propose an idea, make sure to explain why you think it is important. After all ideas are discussed, the class will decide as a group whether to adopt any of the suggestions.

Self Check

Complete this Self Check by yourself.

  1. What is the area of the regular hexagon? What is the area of the circle? Compare the two areas.
  2. What is the perimeter of the regular hexagon? What is the circumference of the circle? Compare the two lengths.
  3. If the figure were redrawn at a scale of 1 cm : 2 ft, what would the area of the regular hexagon in the drawing be? What would the area of the circle be?
