Great for a multi-subject unit! This project uses skills from both math and social studies. Students will have a great time creating their own company by creating a product to sell. They do lots of math work to understand profits and losses. Towards the end of the project, they are able to participate in a "selling simulation" where they get to "sell" their product to their classmates. I used this project with students in grades 4, 5, and 6 and all of my students loved the project!
