The Global Grocery List Project was designed by The Landmark Project and is supported by the Global SchoolNet Foundation. Through the Global Grocery List Project students share local grocery prices to build a growing table of data which is then available to use for computation, analysis, and conclusion-building within the context of social studies, science, mathematics and other disciplines. Since 1987, the project has collected grocery prices from classes all over the world. The website provides information on how to participate and posts the grocery list to use for students in the U.S. as well as other parts of the world, which are kept separate because of the different units of measure and currencies in use. A class can participate at no cost by filling out an online form that includes their local grocery prices and can also view prices already posted by using a search form. Teachers can also read about lesson strategies that have been submitted by teachers using the project and by the project coordinator.
