Linear Equation Generator (4 Difficulty Levels)

This interactive GeoGebra example is a problem generator for linear equations, producing random practice questions across four difficulty levels. It demonstrates how to dynamically create algebraic exercises using randomization and user input. Core math concepts include linear equations in one variable, equation transformation, moving terms, combining like terms, and solving for the unknown. The construction uses GeoGebra commands such as Random, RandomElement, Sequence, and Union to generate random coefficients and constants, while Textfield and InputBox objects allow users to type answers. Key objects include lists (list1, list2, list3) storing random values, variables (a, b, c, d) for coefficients, text objects (text1–text9) for displaying questions and feedback, and answer variables (ans1–ans4). A button (button1) triggers new problem generation. Suitable for middle school math classes or self-study, this tool helps students practice solving linear equations with immediate feedback and adjustable difficulty.
