Lesson 5

The Haunted House

Est. Class Sessions: 1

Summarizing the Lesson

Discuss the ending to the story.

Ask:

X
  • Are there other students they could suspect?
  • Which students? Why?

Students should be able to justify their answers using the data. Some students may respond that Heather's footprint has the same length and that an area of 48 square centimeters is close enough to consider her. The general rule of 10% higher or lower than the estimated measurement would account for any measurement error or differences in estimating when measuring curved shapes making 48 square centimeters “close enough.” Others may think that 48 square centimeters is not close enough given that both measurements for Brian and John are closer to that of the ghost.

Compare Your Footprint. Refer students to the Haunted House Footprint page in the Student Activity Book.

Ask:

X
  • Do you think you would have been a suspect in the story?
  • How can you find out? (Measure the area and length of your foot.)

Ask pairs to help each other trace a foot on the Haunted House Footprint page.

X

If a student's footprint is larger than the grid provided on the Haunted House Footprint page provide a sheet or two of the Centimeter Grid Paper Master.

X

Use the Haunted House Footprint pages with the Feedback Box in the Student Activity Book to assess student progress toward finding the area of shapes with curved sides by counting square units [E3]; making generalizations about a data set using a data table [E8]; showing their work [MPE5]; and using labels [MPE6].
