Link(s) to Alberta Mathematics Curriculum Outcomes:
- Demonstrate an understanding of addition and subtraction of integers, concretely, pictorially and symbolically. [C, CN, PS, R, V]
- Demonstrate an understanding of oral and written patterns and their equivalent linear relations. [C, CN, R]
- Conduct a probability experiment to compare the theoretical probability (determined using a tree diagram, table or other graphic organizer) and experimental probability of two independent events. [C, PS, R, T] [ICT: C7–3.2, P2–3.4]
Brief Overview of the Lesson:
The students will brainstorm the factors that influence people when making a decision. Then they will play a decision-making math game on the Internet. After playing this game, they will discuss the challenges and problems they experienced while playing the game. This will help them to see the importance of knowing all the factors that influence the decision making process.
Estimated Time Required for Implementation:
One class period
Computers, Internet access
Suggested Implementation Strategy:
- Organize the class into groups and ask them to brainstorm and make a list of all the factors they would consider before making a decision about what kind of shoes to buy—take into consideration past experiences, biases, advertisements, cost, individual differences, personal preferences, and peer pressure, etc.
- Take up their responses.
- Ask the class what they would do if their decision turned out to be a bad one.
- Ask them if they know what “opportunity cost” is. (When one choice is made, something else is not chosen. For example, if a person spends money to by “X” product, then they may not be able to buy “Z” product.
- Ask students to form pairs and then tell them to access a game called “The Coffee Shop Money Game” on the Internet at: http://www.coolmath-games.com/0-coffee-shop/index.html
- Tell them that they will choose a name for and set up their own shop. Students will have to identify the opportunity cost, make decisions, and make any necessary changes in order to make their business successful.
Options for Consideration:
- Ask the class to discuss with their family members what factors are important to them to consider before making purchases.
Extended Learning Opportunities:
- The students could research how much money is spent on advertising and how ads are developed to ensure successful marketing.
