Introduction
Students will learn how to collect data and then display that data using line graphs, bar graphs and stem and leaf plots utilizing a computer graphing program. Students will choose specific elements of fitness on which to collect each group of data. The data collected can be used to track personal fitness, and or compare the physical fitness of the student to others.
Prerequisite Experience
Prior to this lesson, so that Microsoft PowerPoint can be used, respectively, for quantitative and presentation tools, students and teachers should be familiar with the program.
Teacher Prep Time
1-2 Hours

Project
Tables, surveys, and stem and leaf plots will be created. Students will then print and paste, or manually transfer this to a tangible paper that can be hung in the class. Students will be asked to create powerpoint to display and analyze their data. This will include drawing conclusions and making predictions based on the data.
Assessment/Grading
An evaluation rubric has been provided to use in assessing the presentations and knowledge of stem and leaf plots.Time Management Tips
Students will work together in groups. This will help students collect the data necessary to complete the graphs. Group members should choose or be assigned to specific tasks so that the workload is split equally, and the project is completed in a timely manner.Lesson Plan Details
Engage
Students:
Watch the YouTube Video on a stem and leaf plot of median ages based on the 2,000 census.
Based on the YouTube video that you saw discuss how you could use a stem and leaf plots to display data that you might collect.
Teachers:
This gives a real life connection for stem and leaf plots. However it does move beyond two digit whole numbers into integers and decimals. Be sure to explain the connections and difference to your children.

Explore
How are graphs used in the school?
Students will be given 30 minutes to tour the school in search of graphs. When graphs are located they will need to ask the creators questions to determine why the graphs are created and what they are bring used for.
What are the different types of graphs and what are they used for?
Students will explore different types of graphs and their uses using the following website. http://nces.ed.gov/nceskids/createagraph/
• Please direct students to experiment with bar graphs, line graphs, and pie graphs.
Students can:
- Choose a Design (bar, line, pie)
- Insert Data (This can be created)
- Choose Labels (Check labels for comprehension of concepts)
- Preview (This is a great time to talk about editing and revising!)
- Print and Save
Explain
Students:
With a partner, or small group formulate a question to which you might collect varied two digit data. Survey as many people as possible, by asking your question and reporting their responses. Together you will create a stem and leaf plot of the data collected.
Share your stem and leaf plots with the rest of the class. Does everyone's plot look the same? Explain why or why not.
Work with a partner or small group to create your own Powerpoint Presentation showing a stem and leaf plot and analysis for the data that you collected. Be sure to draw conclusions and make predictions based on the data.
Your presentation should include the following slides:
1. Title Slide with a description of the data being plotted, and the names of all group members
2. Stem and Leaf Plot. Your raw data should also be included on this page. (A list of the numbers)
3. Conclusions Drawn (You must list at least 5 conclusions drawn from the data, and a short explain as to how you drew them.)
4. Predictions Made (You must list at least 5 predictions made from the data, and a short explain as to how your made them.)
* You may jazz up your powerpoint with anything else that you would like to include, but you must have the four first slides.
Teacher:
This web site will help solidify the students' understanding of stem and leaf plots.

Elaborate
On your own create two more slides for your powerpoint presentation. One must be a new set of data with a stem and leaf plot of the data. The other should have conclusions and predictions based on the data. Share your first slide with your classmates and have them draw conclusions and make predictions, then show them your predictions and conclusions.
Discuss which are the same and which are different, and why.
Evaluate
You will analyze other groups' data and make predictions and draw conclusions based on their data. Your analysis of the other groups data will be graded to help determine your ability to read the stem and leaf plots, draw conclusions, and make predictions. The groups will be graded using the rubric listed below for the Powerpoints, readability of your stem and leaf plots, predictions made, and conclusions drawn.
| Criteria
| Unsatisfactory | Needs Improvement | Satisfactory
| Exemplary
|
| Composition of Stem and Leaf Plots | Data is completely inconsistent with the data presented in the graph (More than 4 errors) | Data is somewhat consistent with the data presented in the graph. (3-4 errors) | Data is mostly consistent with the data presented in the graph (1-2 errors) | Data is completely consistent with the data presented in the graph (No errors) |
| Predictions and Conclusions (Must have at least 5 of each!) | Predictions and conclusions are completely inconsistent with the data presented in the graph (More than 4 errors) | Predictions and conclusions are somewhat consistent with the data presented in the graph. (3-4 errors) | Predictions and conclusions are mostly consistent with the data presented in the graph (1-2 errors) | Predictions and conclusions are completely consistent with the data presented in the graph (No errors) |
| Powerpoint Presentation | Technology was used with little purpose | Technology was used with some purpose | Technology was used with purpose
| Intuitive technology use with specific purpose |
| Overall Final Project | Inconsistent and inappropriate aesthetics and technical functionality
| Somewhat consistent and appropriate aesthetics and technical functionality | Consistent and appropriate aesthetics and technical functionality | Consistent, creative and appropriate aesthetics and technical functionality |
Extend
These ideas can be used to extend the lesson into other parts of the day.
1. Graph of the Day: Present graphs in different forms each day. This could be line graphs, bar graphs, and or stem and leaf plots.
2. The graphs can be analyzed to find the mean, median, mode, and range of the set of data.
3. Analyze the data in the graphs to draw conclusions and make predictions.
Students can create their own needs for data and analysis throughout the year. This data can then be collected, displayed and analyzed. Press students to use the data to make predictions, draw conclusions, and ultimately make decisions!
