Instead of bringing your Ss to a grocery store, bring the grocery store to them! I created an interactive grocery store that allows students to select any item and see the nutrition label and ingredients within that product. You can use it to create a grocery store challenge where students have to put together a meal or find the healthier options within each category. Allows them to not only have the literacy part of food labels but also challenges them to evaluate the nutritional aspect of each item.
