① This interactive game lets students practice solving simple inequalities by randomly generating problems and entering solution sets. ② Key math concepts include solving linear inequalities, using inequality symbols, representing solution sets, and visualizing inequality regions on the coordinate plane. ③ Construction highlights: it employs GeoGebra commands such as RandomElement, Random, If, Circle, and Simplify, and creates objects like ListIneqSymGenerated and SelectedIneqListIndexNum for dynamic inequality generation and display. ④ Suitable for: middle and high school algebra classes, ideal for classroom drills and independent practice.
