This example demonstrates how to find equivalent fractions using the concept of area. It involves basic fraction concepts and the properties of equivalent fractions. Using GeoGebra commands such as Vector, If, Textfield, etc., users can dynamically explore the relationships between fractions. Suitable for high-grade elementary and junior high school students to learn about fractions and equivalent fractions.

GeoGebra Commands & Parameters

  1. Vector((0, 2)) → j
  2. Random(2, 10) → Denom1
  3. Random(1, Denom1 - 1) → Num1
  4. If(Denom1 < 7, (Denom1 * Random[1, 6]), (Denom1 * Random[1, 4])) → Denom2
  5. Textfield(Num2) → inputBox1
  6. Sequence(Rectangle[40 / Denom1, ((k * 40 / Denom1), 2), ((k * 40 / Denom1), 0)], k, 0, Denom1 - 1) → list1
  7. Sequence(Rectangle[40 / Denom1, ((k * 40 / Denom1), 2), ((k * 40 / Denom1), 0)], k, 0, Num1 - 1) → list2
  8. Sequence(Rectangle[40 / Denom2, ((k * 40 / Denom2), -1), ((k * 40 / Denom2), -3)], k, 0, Denom2 - 1) → list5
  9. Sequence(Rectangle[40 / Denom2, ((k * 40 / Denom2), -1), ((k * 40 / Denom2), -3)], k, 0, Num2 - 1) → list3
  10. Point(f) → A
  11. OrthogonalLine(A, f) → g
