Area & Perimeter Session Flow
Important Classroom Rule: When students complete a pathway, remind them to click Download Certificate. Closing the browser tab deletes all calculations and score records immediately.
Why Session Storage is Used
Area & Perimeter is designed for focused classroom lessons where each student solves shape pathways during a single period. By storing answers in sessionStorage rather than permanent cookies:
- Students never see the previous period's answers or pre-solved puzzles.
- The next class starts with a clean slate automatically as soon as the tab is closed.
- Students generate their own physical or digital proof of learning via the PDF certificate.
