Graphing lesson plan

Graphing lesson plan

Excerpt From this Document

Objective

Students will learn how to graph information. They will understand the value of graphs for displaying and analyzing data.

Appropriate for grade 3

Materials: 1 cm square grid paper

Procedure

  • Collect information from students by asking questions such as, "Who has a dog?" "Who has a cat?" "Who has another kind of pet?" and "Who doesn't have any pets?"
  • Write down the number of responses for each question on the overhead projector or blackboard.
  • Discuss with the class different ways of comparing this information. Take class suggestions. If necessary, mention the idea of trying to "picture" the information.
  • After the discussion and trying students' ideas, make a bar graph on the overhead projector from the information collected in your survey. Make sure to demonstrate how it's made and what each section of the graph represents.
  • After the graph is complete ask, "What kind of pet is most popular in this class? Which is least popular? How can you tell? What is a benefit of graphing the information?"

Independent Practice

  • After discussion, have students survey classmates to find out each student’s favorite subject in school (or favorite food, or favorite color, etc.). Give them about 15 minutes to collect info (time may be adjusted as needed).
  • After survey is complete, put students into groups of 2-3 and have each group graph the data they’ve collected. Leave the example on the overhead projector for them to use as a reference.

Summary

When the graphs are complete, have students explain what they learned from the information in the graph. What conclusions can be drawn (e.g., favorite subject overall? least favorite?). Allow students to discuss and question.

Competency Goals from the NC Standard Course of Study
