Students will launch the geometric design challenge, experience the need for precision with compass-and-straightedge tools, and begin identifying the measurable criteria, construction skills, and communication habits they will need for the larger project.

Students will investigate successful circle-based designs, define measurable criteria and constraints for their own work, practice the formal constructions needed for planning, and produce a team-ready design brief with a tested workflow for the next phase.

Students will compare multiple circle-based design approaches, justify one with evidence, build a rapid prototype using formal constructions, and test accuracy, balance, and alignment with measurement data before revising.

Students will use test evidence and feedback to revise their circle-based geometric designs, verify improvements with the same measurements, and prepare a concise engineering-style presentation that explains their criteria, trade-offs, revisions, and remaining limitations.

Students will present their finished circle-based geometric design boards to an authentic audience, explain the geometric reasoning and engineering decisions behind their work, gather audience and peer feedback, and complete a final evidence-based reflection on revision, accuracy, and design choices.
