Everyday Math 5.9Bar and Circle Graphs

• Objective To construct and label bar graphs and
  to discuss properties of circle graphs.

2
Vocabulary

• Bar graph A graph that shows relationships in
  data by the use of bars to represent quantities.
• Circle (or pie) graph A graph in which its
  interior are divided into parts to represent the
  parts of a set of data. The whole circle
  represents the whole set of data.

Tally

• On the board I have listed the 5 snack choices on
  page 152 in your Math Journal. Please come to the
  board and put a tally mark next to the snack you
  chose. Then look at problem 2 in your journal and
  record our class votes.

• A title that describes what is being graphed
• A list of the groups or categories for which bars
  are drawn

Circle Graph

• As a class we are going to go outside and use our
  statistics from the board and make a circle
  graph. If you like a certain snack you will grab
  a certain color of construction paper and I want
  you to stand together in our circle. Meet me
  outside.

Creating our own graphs

• We will be going to the computer lab and practice
  making graphs. This site will give you fun and
  exciting information about collecting data. I
  will fist show you the information and how to
  access it. Then you will be able to go into the
  computer lab, only working on this site and
  practice making graphs. Bring your data sheet.
