Lesson Plan
Provide students with the U.S. Christmas Tree Sales work sheet. The work sheet provides a line graph showing Christmas tree sales from 1993 to 2000. Students study the work sheet and answer the questions on it. This work sheet can be used as a homework assignment to be corrected in class, or as a classroom activity. (See Answer Key in the Assessment section below.)
More Challenging Questions
The questions on the work sheet are targeted at students in grades 2-4. If your students are older, you might want to post on a board or chart additional questions for students to answer. Following are five possible questions:
Extend the Lesson
Have students create a bar graph showing the following information about household use of Christmas trees. The information shows the percent of homes that had real, artificial, and no tree in 2000.
Real Tree 31 percent
Artificial Tree 49 percent
No Tree 21 percent
Source: National Christmas Tree Association (NCTA), Industry Statistics. Note: Numbers total 101 percent because some respondents said they had both a real and artificial tree.
After creating the graph, conduct a survey of students to learn which of their families have real, artificial, and no trees. How do students personal data compare to data collected nationally by the NCTA? Students might use the free online Create a Graph tool to make a graph that illustrates the results of their own survey.
Assessment
Have students write a paragraph or a brief essay comparing Students will score at least 80 percent on the U.S. Christmas Tree Sales work sheet. In addition, you might have students write a paragraph in their journals explaining how the data they collected compares to national data collected in 2000 by the National Christmas Tree Association.
Answer Key: 1. 32 million; 2. 1993; 3. 1998; 4. 4 million (sales grew from 33 million to 37 million); 5. up; 6. 67 million (35 million + 32 million).
