① This interactive example generates linear inequalities with the variable on one side for students to solve, allowing them to enter the solution set and receiving immediate feedback on correctness. ② The core mathematical concepts include solving one-variable linear inequalities, representing solution sets in interval notation, and understanding inequality direction rules. ③ Construction highlights: using GeoGebra commands such as Random, Sequence, Union, RandomElement, Textfield, and FractionText to generate random coefficients and constants, with InputBox for student input, and slider, button1, and multiple text objects for interactive feedback. ④ Suitable for middle school or early high school algebra, this tool serves as a practice drill, classroom demonstration, or self-study aid to reinforce inequality solving skills.
