Self-Assessment Practice on Inequality Symbols

This interactive GeoGebra example is a self-assessment tool for practicing the use of inequality symbols such as <, >, ≤, and ≥. It randomly generates inequality problems, prompts the user to select the correct symbol, and provides immediate feedback, reinforcing understanding of the direction and meaning of inequalities. The core mathematical concepts include basic properties of inequalities, semantics of comparison symbols, and comparing magnitudes on a number line. In terms of construction, the example employs GeoGebra commands such as Textfield, Random, and SelectedIndex, along with objects like textFeedback1 (feedback text), inputBox2 (input box), correctanswer (correct answer), SymbolList (list of symbols), InequalityList (list of inequalities), button1 (button), and numerous auxiliary points (A1 to A23) and lists (list1, list1add, etc.) to dynamically generate questions, check answers, and display feedback. This resource is suitable for middle or high school students for classroom practice or self-study, serving as a formative assessment tool for inequality symbols, and can also be used by teachers to create interactive quizzes.
