Solving Absolute Value Equations: Interactive Practice and Verification

① This GeoGebra example demonstrates how to solve absolute value equations through an interactive interface, where students input equations and verify their solutions step by step. ② The core mathematical concept is solving absolute value equations, involving the geometric interpretation of absolute value as distance on the number line and algebraic methods such as case analysis. ③ Construction highlights: from the construction summary, it uses Textfield, Sum, inputBox, button for interactive input and control, objects like a, b, c, f to store coefficients and expressions, lists and attempts to track student responses, and text objects to display feedback. ④ Suitable for middle school to high school students learning absolute value equations, useful for classroom practice, self-study, or formative assessment, helping students understand solution methods and verification strategies.
