A classic manipulative, used since the 1960s, continues to offer opportunities for intriguing problem solving involving proportions.
Hyewon Chang and Barbara J. Reys
Using Clairaut's historic-dynamic approach and dynamic geometry tools in middle school can develop students' conceptual understanding before they encounter formal proof in geometry.
Dongjo Shin, Ryan C. Smith, and Somin Kim
Use a framework to evaluate a tool: Is it mathematically sound? Does it offer opportunities for student engagement with little distraction? Will it afford students the chance to develop their own ideas?
