Leisure time activities are a great way to pursue interests outside of schooling and work. They can also be a way to manage stress and build relationships with family and friends. While recreational pursuits can help us maintain a healthy lifestyle, too much of a good thing can also be detrimental to a person’s well-being.
According to Statistics Canada, young people aged 12 to 17 “spend an average of 20 hours each week in front of a screen.”1 This time includes watching television, playing video games, and using computers. Only 13% of Canadian youth are meeting Canada’s physical activity guidelines of 90 minutes of physical activity a day. This is an alarming rate of physical inactivity!

Moreover, researchers have found that physical activity levels currently decline with age and gender. Teens are less active than children, and girls are less active than boys. Inactivity is a concern because it contributes to unhealthy weight levels and increased blood pressure—risk factors for heart disease and stroke. In fact, there is a linear relationship between body-mass index—a measure that compares one’s weight and height—and blood pressure. The higher the body-mass index, the higher the blood pressure. Both stress and inactivity can lead to high blood pressure. High blood pressure, in turn, increases one’s risk to stroke, heart attack, kidney failure, and other adverse health conditions.
Are you physically active? If not, taking charge of your fitness may be one of the best decisions you will ever make in order to promote health and wellness. The Heart and Stroke Foundation of Canada estimates that inactive people who begin a program of physical activity can reduce their risk of heart attack by 35% to 55%. The key to keeping exercise a part of your life is by finding a physical activity that you enjoy and that you will keep on pursuing in your leisure time. You have many options—some examples are walking, bicycling, dancing, skateboarding, golfing, cross-country skiing, and participating in team sports or exercise classes.
Throughout this course, you learned that math isn’t reserved for the classroom only. Mathematics is a way to describe and understand our surroundings. In this module you learned how linear equations can be used to model and describe recreational pursuits such as art and scuba diving. You learned, for example, that whether you are composing music, listening to music, or purchasing music online, you can use the mathematics of linear equations to explain what is happening and predict what will happen in the future. In this module you deepened your understanding of linear functions by working through interactive lessons, multimedia pieces, and project assignments.
The Outcomes for Module 6 table summarizes the learning outcomes in this module. As a review of what you have learned, complete the table by identifying those activities you undertook to address the corresponding outcomes. An example of what the table could look like can be found in the Unit 1 Summary. Please save a copy of this completed table with your work from this module in your course folder.
In the next module you will learn how to solve a system of equations. A system of equations is a set of two or more equations whose solution is the set of values that satisfies all equations in the system. You will learn how to solve linear systems by graphing techniques as well as algebraic ones. Again, you will learn the math concepts in the context of leisure time and hobbies. The project work will focus on a vacation experience where you can discover and engage in multiple recreational pursuits.
