Lesson: Graphing Differences Length: 15 minutes
Foundation: Mathematics: Problem Solving-Ability to Reason, Predict, and Problem
Solve Through Exploration
Age Intended: Preschool
Performance Objectives:
-The students will be able to recognize a way they are different than their peers.
-The students will be able to participate in creating the graph.
Advanced preparation by teacher:
-The teacher will need to have paper ready that is appropriate for graphing.
-The teacher will need to have colored pieces cut out to be displayed on the graph.
-The teacher will need to have colored markers to represent the different hair colors.
Procedure:
Introduction/Motivation: The teacher will ask the students if they can name some qualities about themselves that are different than their peers.
Blooms critical thinking questions to ask along the way:
-Level 1-Knowledge
1. Which hair color do most students have?
2. Can you select the color of hair that the least students have?
-Level 2-Comprehension
1. How would you compare the blonde hair to the black hair?
2. What can you say about the graph?
-Level 3-Application
1.What other way could you show your hair colors?
2. What would result if no one had brown hair?
-Level 4-Analysis
1. What are the different parts of the graph?
2. Why do you think more people had brown hair than red hair?
-Level 5-Synthesis
1. Can you choose a different topic for the graph?
2. Can you predict the outcome of the graph? How?
-Level 6- Evaluation
1. How would you prove that more people have brown hair than red hair?
2. How could you determine what color of hair most people in the class have?
Step by Step Plan:
1. The teacher will announce that today they will be making a graph that will show how the students are different from one another.
2. Then ask the students to think to themselves about the color of their hair.
3. Begin drawing the graph.
4. Draw a line on the left hand side, that represents the number of students.
5. Then make marks according to how many students are in your class (for example five, ten, fifteen, twenty.....).
5. Draw a line across the bottom of the paper that represents the color of the students hair.
6. Label an area for each color (for example red, blonde, black, or brown).
7. Next have the students come up each one by one and select the piece of precut construction paper that best represent the color of their hair.
8. Then the student will place their hair color in the appropriate column.
Closure: After every student has gone. The teacher will discuss the results of the graph. The teacher will then discuss the way this graph represents the student’s differences.
