Monthly Cost of Living - Food

by Ric Cooley

Learning Objectives:

Students will learn how much it cost to feed a family. This lesson con be part of Sex-ed Family Life along with real life math.

Grade Level: 4-7

Materials:

Resources:

The Internet SuperCenter (http://www.netgrocer.com)
thefoodstores.com (http://thefoodstores.com)

Activities:

  1. Students will be placed in an imaginary job situation where they are making $2.00 per hour above minimum wage. From this they will find out how much money they are making per month.
  2. Teacher will give group the Monthly Cost of Living Worksheets
  3. Students will brainstorm in small group to come up with 1 weeks worth of menus. They will then breakdown what food items are needed to buy at the store. After the breakdown of items students will go to the Internet and shop, collecting the cost of each item, add it all up for the week, then times it by 4 for the month. Students should only spend between 1/4 to 1/3 of their monthly income.
