Geometric ConstructionSlider Animation
This example demonstrates how to represent the shaded part of chocolate bars using fractions. The core mathematical concept involved is fractions. Using GeoGebra commands such as Random, If, Point, Segment, Vector, and Polygon, dynamic geometric figures can be constructed. Suitable for high-grade elementary or junior high school students to learn about fractions and their applications.
