Exploring the Product Property of Roots

This GeoGebra activity interactively demonstrates the product property of roots by guiding students to see how multiplying root expressions produces a simplified result. Key concepts include radical expressions, the multiplication rules for roots, and strategies for simplifying expressions under/with radicals. Construction and interactivity are driven by controls and data handling: SelectedIndex manages the workflow/selection state, while Shuffle and Element are used to pick and access the underlying items for questions. Variables such as is, allA/allB, factA/factB, countQuestion coordinate the generated facts and tracking, and prod stores the computed product. The interface uses animation and navigation elements (btnAnim, btnRewind, ddMenu, aniSli, captionSli, tabOrder) and on-screen text (textQuestion, textStep) to display prompts and reasoning steps. Suitable for grades 9–12 in lessons or independent practice focused on simplifying radical expressions and building deeper understanding of root operations.
