Introduction to Bar Graphs Lesson Plan
This lesson allows students to learn what bar graphs are used for, how to interpret the data presented,
and how to organize their own data using bar graphs.
Data Analysis and probability
Formulate questions that can be addressed with data and collect, organize, and display relevant
data to answer them
Select and use appropriate statistical methods to analyze data
- design investigations to address a question and consider how data-collection methods
affect the nature of the data set;
- collect data using observations, surveys, and experiments;
- represent data using tables and graphs such as line plots, bar graphs, and line graphs;
Students must be able to:
- perform basic mouse manipulations such as point,
click and drag.
- use a browser such as Netscape for experimenting with
Students will need:
- access to a browser.
- access to pencil and paper.
- Focus and Review
- Begin by calling on each student in the class and asking what color his/her eyes are.
- As each student answers make a tally mark by the appropriate color.
- Ask the students to arrange the information displayed on the board in a way that it is easy
to read on a sheet of paper.
- Monitor the students' progress.
- practice making bar graphs.
- be able to interpret bar graphs.
- ask a question, collect data about that question,
and create a bar graph to answer their question.
- Teacher Input
- Congratulate the students on their efforts.
- If any student happens to arrange their information in a bar graph-like-manner use
his/her graph as an example.
- If not, explain to the students that some people choose to arrange their data
in what is known as a bar graph.
- Explain the term bar graph.
- Explain how to arrange data using a bar graph.
- Guided Practice
- Have the students help you arrange the data located on the board into a bar graph.
- Describe to the students how to use the Bar Graph Shape Sorter applet.
- Instruct the students to run through several sets of shapes to get a feel for the program.
- Record information about the types of pants people are wearing
(Pants, jeans, dresses, or shorts).
- Instruct the students on how to use the
- Have the students use the Bar Graph
applet to graph the data collected about what type of pants people in the class wear.
- Independent Practice
- Instruct the kids to come up with a question they would like to answer
by surveying their classmates.
- You may want to give them a few sample questions to choose from if they
cannot come up with one on their own:
- Shoe Size
- Birth Month
- Favorite Color
- Hair Color
- Favorite Book
- Favorite Television Show
- Have the students question their classmates and then create a bar graph
either on paper or by using the Bar Graph applet
- Choose several students to share their bar graphs with the class.
- Cover all pertinent vocabulary.
For younger students, you may want to hand them a bag
of shapes and have them create a bar graph similar to those found in the
Bar Graph Shape Sorter
applet, rather than having them survey the class and creating a bar graph using the Bar Graph applet.
