Pumpkin Seed Data!
Emily Vander Kooy
DescriptionHow many seeds are in a pumpkin? Find out in this lesson! [NOTE: This lesson is designed for a grade level in which students change classes. It is easily adaptable for self-contained classrooms.]
ObjectivesThe student solves problems by generating, collecting, organizing, displaying, and analyzing data using histograms, bar graphs, circle graphs, line graphs, pictographs, and charts.
Materials-Pumpkin Day worksheet (associated file)
-Pumpkin Day Graph Paper (associated file)
-Overhead transparency of worksheet and Graph Paper
-Four Overhead pens, different colors
-Newspaper or Butcher paper
Preparations1. Duplicate Pumpkin Day Checklist (associated file), Pumpkin Day Math Activities (associated file), and Pumpkin Day Graph (associated file)for each student.
2. Prepare overhead sheets of Pumpkin Day Checklist (associated file), Pumpkin Day Math Activities (associated file), and Pumpkin Day Graph (associated file). Or make poster size paper graph if you choose.
3. Purchase 4 pumpkins.
4. Cut the top of each pumpkin open.
5. Cover student desks with newspaper.
ProceduresNote: This lesson addresses generating, collecting, organizing, displaying, and analyzing data using bar graphs.
1. Display four pumpkins in the classroom.
2. Ask students, How many seeds do you think are inside?
3. Tell students that today we are going to find out how many seeds are inside these pumpkins.
4. Ask – "Can you estimate how many seeds are inside each pumpkin?"
5. As a group, class lists different forms of estimation on the board.
6. Ask – "Which form of estimation would give us the most accurate estimate?" Answers will vary.
7. Distribute Pumpkin Day Graph (associated file).
8. Allow time for students to make their estimates. Students will make their estimates on the pumpkin graph below where their actual answers will be located.
9. Explain to students that since we have made our estimates, we will now find out how many seeds are actually in the pumpkins!
10. Bring one pumpkin to the front of the classroom on a pre-covered surface. Take the precut lid off of the pumpkin.
[For each of the four classes teacher will use a different pumpkin.]
11. Explain to students:
- They will come up in pairs and remove a handful or two of pumpkin seeds from the actual pumpkin.
-They will take the seeds back to their desk, which is covered with newspaper.
-They will separate the seeds into piles of 10.
-When all students finish counting, we will add everyone’s total to come up with a class total.
12. Allow time for students to come and extract the seeds from the pumpkin.
13. Circulate around the classroom, check to ensure students are counting their seeds accurately.
14. After students finish counting, list each group’s total on the board.
15. As a class, add all numbers for a class total of pumpkin seeds. At this time you have a total number of seeds in that pumpkin. Compare student estimate to their actual answer. Discuss reasonableness of estimate.
[After all four classes have completed this activity, list all pumpkin totals on board for use on Day 2.]
16. Display all four pumpkins, labeled with their total number of seeds. Explain to students that we will be organizing, displaying, and analyzing the data (number of seeds).
17. Demonstrate graphing the pumpkin estimates and actual totals using the overhead projector or large graph on chart paper. Be sure to include the graph title, labels, and data.
18. Allow students time to complete their graphs - using Pumpkin Day Graph(associated file) , including all four pumpkins.
19. Distribute Pumpkin Day Checklist (associated file) to students, with a partner, they will evaluate each other’s graph. Students can make necessary changes.
20. Collect student graphs.
21. Distribute Pumpkin Day Math Activities(associated file).
20. Explain questions listed on the handout.
22. Using graph on the overhead (or chart paper), answer questions on Pumpkin Day Math Activities (associated file) handout.
23. Allow students time to complete their handout.
24. Encourage students to check their work. Collect Pumpkin Day Math Activities (associated file)handout.
AssessmentsNote: This lesson addresses generating, collecting, organizing, displaying, and analyzing data using bar graphs.
Students complete a double bar graph and analyze data with a worksheet (associated file). Use the Pumpkin Day Checklist (associated file) to assess whether the student created graphs show accurate data collection, data organization and data display
Evaluate the worksheet for 85 % accuracy. Students evaluate peer graphs and provide feedback, before teacher evaluation.
