Expectations Rubric for the project and a beginning sheet is included in the project. I give instructions for the layout and looking for a store, so students can have all the math calculations together. I allow my students free range for the rest as long as they have all the components listed. There are questions in each section, for clarification.
I do this project at the end of the year, so we spend half the day for 3 days working on it. Students do a great job. If there are any questions, I walk around and help students the entire time.
