Every year there is a new fad at school (bracelets, duct tape pens, baked goods, etc) and the students think they are going to go into buisness and make their millions. This gave me the idea to make a math project about a buisness (after all, the kids learn more when they are interested in the lesson). The students pick a product, name their business, figure out costs, profits, time involved, etc to determine if their business will be sucessful. I use this with my 6th graders, but i think it could easily be adapted to work with 7th or 8th grade students as well.
