As a final project, I like to find a way to incorporate a social justice lesson into the eighth grade curriculum. Last year, the class spent the final weeks of the year tackling the question, "Is minimum wage a livable wage?" They explored by calculating living expenses for a year (rent, food, transportation, entertainment, etc) and then compared it to what you would earn if you were working a minimum wage job. They had a a guest speaker from the Human Resources department come and talk about the taxes and deductions that are taken from a pay check. In the end, we had a good debate/conversation about whether or not you can live off of minimum wage.
This year, the class took on the idea of food deserts. This is a project I have been tossing around for about a year. The essential question was, "What is a food desert? Who is impacted by food deserts?" We researched and defined a food desert. They looked at research about the impact of food deserts. For four classes, a group of students were charged with locating grocery stores on a set of maps from AAA of the Bay Area, Lake Tahoe, and Portland, OR. They had to cut out 1-mile radius circles to represent the reach of the grocery store. The areas that were not covered by the circles are defined as food deserts. These maps are not comprehensive because we were limited in time, but students were able to get a sense of how food deserts occur and who is impacted by these deserts.
Our discussions centered around how they live in an region of the country were access to fresh fruits, vegetables, dairy, and whole grains is easy. They recognized the high density of markets and grocery stores is high in the Bay Area and that affluent areas had great overlap of circles. Some students were able to recognize living in Northern California is not representative of the issue of food deserts. If we had more time and I had planned ahead, we would have done a second round of maps that represent cities where food deserts are a significant issues, such as New Orleans, Atlanta, and Detroit, and compared maps with the Bay Area. I would extended this to look at grocery stores per capita and other ratios that might have helped us understand the issue.
This activity turned out better than I had hopes and I was pleased with how we were able to use math to explore this topic. I look forward to refining and extending this project for future classes.
