of the Future
Essential Understanding: Graphical mathematical models or representations can be used to solve problems and describe results.
Indicators:
Students will analyze graphs, compare
the information that is represented and determine if one graph is a better
representation than the other.
Students will interpret and describe situations
mathematically.
Technology Indicators:
Graphs serve a useful purpose. They are an organized way to represent data. There are many types of graphs. Some graphs you may be familiar with are bar graphs, line graphs, pie graphs and pictographs. Each of these types of graphs compare data or show change over time.
The Growth Spurt graph really caught your attention because it had great graphics. Look at the pictograph below. Based on your training you notice that this pictograph is missing a key. Before answering the following questions look at the graph to determine what an appropriate key would be.
Open a word processing program to answer
the following questions. Be sure to answer each question in R.A.R.E.
form.

The line graph shows change over time. Click on the link below to view the graph. To return to the miniQuest click the back button.
Continue to answer the following questions in the word processor from step one.
- What would you label the x and y axis on this graph?
- Does this graph show a similar trend to the pictograph in step one? Explain your response.
Think about the graphs you have just analyzed. Complete an Add Up the Facts organizer to prove that the world population is growing. Be sure to include information from each of the graphs to support the main idea.
