Grocery shopping (QC)

Subject Area: Mathematics

Brief overview

This situation consists of planning the grocery shopping for a four-person family for two days. As a result of this activity, the students will be learn about how to follow a budget, and about taxable and non-taxable food items.

Subject area(s)

Mathematics
• Competency 1: Solve a situational problem
Analysis of the situation, appropriate organization and use of concepts and strategies

Explanation of the teaching goal

– Following a budget
– Awareness of taxable and non-taxable food items

Expected outcomes

Ensure that the students understand that certain choices allow them to save money. Using taxable and non-taxable food items, the students will be able to recognize price differences and will understand how to follow a pre-established budget.

Role-playing

Role-playing can be done by having the teacher ask a series of questions about grocery shopping:
– Have you ever gone grocery shopping?
– Have you ever noticed that taxes have to be added to certain products at the grocery store?
– What products are taxable at the grocery store?
– What is the difference between a taxable and a non-taxable product?

Achievement

Students must plan menus for a four-person family by filling out the table in the appendix. They should buy enough food to last two days, taking into consideration as much as possible the recommendations of Canada’s Food Guide. A table with various grocery products is available in the appendix to make this task easier, and to allow students to make the necessary calculations.
*The teacher may also choose to ask the students to use grocery store flyers.

Appendix: Student file

Your parents ask you to help with the grocery shopping for the weekend. Therefore, you must plan meals for your four-person family. Careful! You should plan to buy food for two days, following as best you can the recommended servings of Canada’s Food Guide.

Your family is made up of your two parents, aged 40, your little 8-year-old sister, and you. You should follow a maximum budget of $100. Use the food table to help you choose the menus and calculate your total grocery bill. Of course, you can use the basic foods that your parents already have, such as flour, spices, ketchup, mayonnaise, etc.

Fill out the following table to determine the meals for each day.
