Next we will be creating a bar graph. I will be asking you which are your favorite colors.  We will go around the room and say our favorite color. After tallying up the number of students who like each color we will create a bar graph. In the board I will draw a graph and then we will create the bars with different color markers. The colored markers will represent the different favorite colors of the students.

The picture below is an example of what our graph will look like.

As a class we will be creating a picture graph. The picture graph will be displaying the different kind of pets we like. I will draw a graph on the board with different kind of pets the class likes on one side. On the other side we will have the number of students in class.
For example, we will have a section for dogs. I will ask how many students like dogs. If 7 students said they liked dogs, we will then draw 7 dogs to represent it. We will do it for every pet a student likes in the classroom.

The picture below is an example of what our graph will look like.

Now it is time to practice! You will apply what we just learned and create your own bar graph! You will ask your classmates what is their favorite sport and record it.

In the future you will be encountering with many different graphs. You will use graphs in future math classes where large amounts of information is displayed. With this lesson you will have an introduction to graphs and how to read and display information.

Graphs will help us read and understand information in a better way. It helps monitor and visualize how things may be increasing or decreasing.

# data[].attributes.body
Graphs are used to interpret information.  Different types of graphs have been around for many years to display and understand information. For instance, Bar graphs were used way back by, "Frenchman, Nicole Oresme used a bar chart in a 14th century publication, "The Latitude of Forms", to plot velocity of a constantly accelerating object against time" (History of Bar Charts and Graphs). Picture graphs have been around for many years as well and were used by Egyptians. "The use of picture graphs dates back to the ancient Egyptians. They used pictures known as hieroglyphics to convey a message" ( Study.com). With graphs you can visually see information and have a better understanding of it. All around the world distinct types of graphs are used that all serve the same purpose, to interpret information.

Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems using information presented in the graph. See Table 1.
