Estimate and calculate the cost of transactions involving multiple items priced in dollars and cents, including sales tax, using various strategies.
Number
Read, represent, compose, and decompose whole numbers up to and including 100 000, using appropriate tools and strategies, and describe various ways they are used in everyday life.
Context
Students explore subsidies and other solutions to high food prices in remote Indigenous communities.
Handout: Determining item cost before subsidy (Appendix B)
Chart: Subsidy levels for Attawapiskat First Nation (Appendix C)
Chart: High, Medium and Low Subsidy Grocery Items (Appendix D)
Example: Using Appendices B, C and D to determine the cost before subsidy (Appendix E)
Lesson
Introduction
After investigating the factors that influence food prices in Lesson 2: Food Prices in Remote First Nations, introduce students to subsidies as a possible solution to offset high food prices.
Lesson
Introduce the concept of a subsidy and show examples of services that receive subsides (Appendix A).
Explain that governments have attempted to offset the high cost of food in Northern Ontario with a subsidy program called Nutrition North. The food prices seen in Attawapiskat (Lesson 2) is the cost of the item minus the subsidy.
Provide your students with Appendix B and ask that they use this handout to aid in their calculations of food costs before the subsidy was applied. To do this, students will reference two charts:
Appendix C shows the varied subsidy applied to items categorized as high, medium, and low;
Appendix Dshows a chart of which grocery items are considered high, medium, and low subsidies.
See Appendix E for an example of the calculations on the chart.
Conclusion
Ask students:
What do you notice about food prices in Southern Ontario and Attawapiskat?
Does the subsidy help to equalize the cost of food between Southern Ontario and Attawapiskat? What else could the government do to help with this?
What other sources of food (i.e., traditional foods) are not being addressed through subsidies?
Look Fors
Can students calculate the amount of subsidy applied to food items?
Can students convert items from grams to kilograms?
