This packet includes instructions for teacher and students. It also includes work pages, an expense page, a teacher rubric for scoring and student rubrics to score each other and themselves. This project will incorporate Science, Social Studies, Math and Language Arts standards. The students will have a good time and work cooperatively. You will need to buy some supplies, but they can be used year after year. This is a great end of the year activity. The students will be working together, designing, purchasing supplies, trading with other teams, building and presenting. It can take as little as one hour, or a few days if you want it to. This packet is not PDF so that you can manipulate the information to suit your student's needs.
