In this Model Eliciting Activity, MEA, students will be asked to rank and choose from the potential docks the Lake Wonder Camp could purchase before next summer based on the data given. In the process, students will need to find area and perimeter as part of their criteria for ranking. The data provided is: dock dimensions, price per square foot for materials, warranty, and material quality. In the twist, students will be asked to calculate the cost of adding a safety bumper around each dock (after finding the perimeter) and calculate the total cost of each dock with the price of the safety bumper added. They must also stay within a $5,000 budget. Students must decide how to change their procedure with the new information.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem, while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought process. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.
