VectorFunctionCoordinate GeometryGeometric ConstructionSlider Animation
This example demonstrates the geometric intuition and calculation process of adding fractions; involves core math concepts like fraction operations, Least Common Multiple (LCM), Greatest Common Divisor (GCD), and vector operations; constructed using GeoGebra commands such as Random, LCM, GCD, and objects like difficulty, d_1, d_2, etc., for dynamic generation and calculation; suitable for middle school and above students to understand the essence and geometric meaning of fraction addition.

GeoGebra Commands & Parameters

  1. Random(2, difficulty) → d_1
  2. Random(2, difficulty) → d_2
  3. LCM(d_1, d_2) → cd
  4. Random(1, d_1 / 2) → n_1
  5. Random(1, d_2 / 2) → n_2
  6. GCD(b, cd) → c

AI Drawing Prompt Reference
