Getting the Best Deal (BC)

Subject Area: Mathematics

Links to the British Columbia Mathematics Curriculum:
  • A2 – demonstrate an understanding of the addition, subtraction, multiplication, and division of decimals (for more than 1-digit divisors or 2-digit multipliers, the use of technology is expected) to solve problems
  • A3 – solve problems involving percents
  • A6 – demonstrate an understanding of addition and subtraction of integers, concretely, pictorially, and symbolically from 1% to 100%
Links to the New Learning Standards:
  • Implement multiple strategies to solve problems in both abstract and real-life situations using different cultural perspectives
  • Develop, construct, and apply mathematical understanding through play, inquiry, and problem solving
Brief Overview of the Lesson:

After a discussion about how to shop for the best deals, the students will complete a worksheet that determines the unit prices for various items. The teacher will lead a discussion by taking up the answers. The students will mark each other’s papers.

Estimated Time Required for Implementation:

One class period

Materials Needed:

Copies of the handout “What’s The Best Deal?”

Suggested Implementation Strategy:
  • Ask the class if they have ever bought something and then found out later that they paid more than they had to pay.
  • What could they have done to avoid paying too much?
  • Ask the class about the strategies people can use to get the best prices, e.g., wait for a sale, buy at the end of the season, use coupons, comparison shop, etc.
  • Hand out the worksheets and tell the class that they are going to compare some prices to find the best deals.
  • Remind the class that may need to convert metric system units in order to answer the questions.
  • Have the students exchange worksheets so they can mark each other’s papers. The class takes up the worksheet answers and discusses which deal is best.
Evaluation:
  • Collect the worksheets to record the marks.
Possible Links to the Home Program:
  • Ages 11-13 – Activities: Local – Shopping List
Extended Learning Opportunities:
  • Ask the students to calculate the difference in the costs for each item.
  • Ask the class to bring in ads, magazines, and catalogues. The students could choose two items and compare prices to find the best deal.
