  6. Summarize • What was easy? • What was difficult? • Are there any polygons in the painting?

  7. What fraction? • About 5 of 27 pieces • 5/27 can be estimated at 5/25 • 5/25 can be simplified to 1/5. • The center field encompasses about 1/5 of the entire painting.

  8. What percent? • Using the estimated fraction of 1/5, I know 1/5 = 20% • The center field encompasses about 20% of the entire painting.

  9. Scale factor of 3? Scale factor of ½? Scale factor of 1.3? Scale factor of 1/8? Scale factor of 75%? Larger Smaller Larger Smaller Smaller Larger or Smaller?
