This photo shows a hockey player skating to a stop on an outdoor ice rink.

In this module you are focusing on sports and recreation. You may choose to answer the questions or contact your teacher if you would prefer to create a graph about a different scenario of your choice.

In hockey, there are many events that can be graphed—for example, number of wins for a team, number of goals for a player, number of penalty minutes. The graphs can help players, coaches, and fans see patterns and trends in the numbers. These patterns allow people to make more informed decisions.

Now it is your turn to create graphs. Your graphs may be based on hockey, or you may choose a sport or recreational activity that is of more interest to you.

Go to the Unit 3 Project, and complete the Module 4: Lesson 1 component.

Going Beyond

In 2009, the H1N1 flu was a large concern. The following graph illustrates the course of the H1N1 flu virus outbreak in Canada. (The graph, produced by the Public Health Agency of Canada, is current as of June 8, 2009.) The illustraton shows either the date when symptoms of the H1N1 flu virus began or, if this date was not available, the date when a specimen was collected for each of the laboratory-confirmed cases.
