This activity is aligned with Math Common Core Standards and has real world application. While I use this activity in my 3rd grade Talented and Gifted class, this project based learning activity can easily be used in a 4th or 5th grade classroom. The product features a lesson plan with two real world scenarios for you to choose from and correlating student guide sheets. Students will need access to the internet or pricing from local nurseries to research material costs, PowerPoint to complete a presentation (optional), graph paper, and measuring tape.
