## There Is No Place Like Home on the Range

### Claudette McCannLeon County Schools

#### Description

Students use data from the real estate guide to find the range, mode, median, and mean of a sampling of homes for sale in their area.

#### Objectives

The student identifies the mean, median and mode from a set of data.

#### Materials

- One “For Sale Sign”
- 5 –10 copies of Homes and Land Real Estate Guide or other Real Estate Guide
- 15 copies of the real estate section from Sunday’s newspaper
- Paper, preferably 10” x 17”
- Scissors
- Glue sticks
- Calculators (can be used because the numbers in this activity exceed the Content Limits of FCAT)
- Student Self-assessment/ Teacher Assessment from attached file

#### Preparations

1. Collect the real estate guides or Sunday real estate sections.
2. Locate a For Sale Sign
3. Prepare (download) student self-assessment/teacher assessment files
4. Have other materials available (See materials list.)

#### Procedures

Prior Knowledge: The student should have an understanding of the terms and procedures involved in finding range, mode, median, and mean. They should be able to do this with and without a calculator.

This activity can be completed individually or in pairs.

1. Hold up a FOR SALE sign and ask the students where they’ve seen this type of sign.

2. When they mention that they’ve seen them in front of houses ask, “How much do you think it costs to buy a house?” As children offer amounts, record the numbers on the board. (Keep the numbers on the board to use in a review of range, mode, mean, and median.)

3. Tell the students that they will be using information from the real estate home finder guides or the real estate section of the Sunday newspaper to find the range, mode, median and mean of a sampling of houses.

4. Review the concepts listed below using the numbers generated from Step 2.

Range - the difference between the highest and lowest numbers in a set of data

Mode - the data point, score, or number that occurs most often in a set of data

Median - the middle point of a set of numbers where half of the numbers are above the median and half are below

Mean - the average of a set of data found by adding the numbers in a set and dividing by the number of addends

5. Have the students get out scissors, a glue stick, a calculator, and a pencil or distribute the supplies if necessary.

6. Hand out a piece of paper and a page from a “Homes and Land” magazine or from the real estate section of the newspaper. Be sure the prices are shown in the description.

7. Direct the students to select any five (5) of the houses from the page and cut out each selected house and its description.

8. Direct the students to arrange the houses in order from least to greatest based on the price. *Check over the placement of the houses before proceeding to the next step. (Peer or Teacher)

9. Have the students glue the houses onto the paper, placing them horizontally from left to right.

10. Have the students analyze and calculate the data to determine the range, the mode, the median, and the mean (average.) The answers should be recorded and labeled on the paper under the cutouts of the houses.

11. Allow about 20 minutes for the students to complete this task.

12. Once the products have been completed, ask the following questions: *See note below.
- What are some things you noticed about the houses you selected? (Price, size, amenities, location)
- What is the difference between the mean price of your sampling and the mean of the “guesses” we put on the board at the beginning of this lesson? Have each child/pair compute the difference and share the results.
- After completing this lesson, if you were asked the mean price of a house in Tallahassee, what would you say? Why would you use that number?

*You may want your students to write their answers on a -Think Pad- before sharing orally with the class. This strategy gives all children the opportunity to -respond- to each question. (A -Think Pad- is just a piece of paper or several pieces stapled together.)

#### Assessments

1. After completing the product, the students will complete the self-assessment (See attachment)

2. The data on the student product will be checked by the teacher and feedback will be given to the student. (See attachment)

#### Extensions

1. Modifications:
- Pair less able students with more capable ones.

- Use items that are less expensive (shoe sales, school supplies, items on a menu, etc.)

2. Extensions:
- Use a web site www.tallahassee-online.com to find an online real estate company. Then follow the directions given in the original lesson.

3. Math:
- Round each house price to the nearest ten, hundred, thousand, ten thousand, and hundred thousand.

- Have students work at the computer on Beacon’s Student Web Lessons :
“All That Data!”, “All That Data, Too”, “The Mean Green Machine”, “The Great Basketball Debate”

4. Language Arts:

- Read the description of each home. List or circle the nouns in each description. Then list or underline the adjectives.

- Compare the descriptions of a very expensive house to one that is less expensive. Prepare a Venn diagram that shows the differences and similarities. Write a paragraph that compares and contrasts those amenities.

- Select one of the houses and write your own description.

5. Career Education: Invite a real estate agent to talk to the class about his/her career choice.
