This example demonstrates the concept of equivalent fractions numerically. It involves core math concepts like fractions, division, upper and lower sums or Riemann sums, rational numbers, line segments, and percentages. Constructed using GeoGebra commands like Random, If, Sequence, and objects such as b, e, a, m, d, c. Suitable for middle school and above students to explore fraction equivalence.

GeoGebra Commands & Parameters

  1. Random(2, 10) → b
  2. Random(0, 1) → e
  3. Random(1, b - 1) → a
  4. Random(2, 4) → m
  5. If(e ≟ 0, (a * m), a) → c
  6. Sequence(Rectangle[20 / d, ((k * 20 / d), -1), ((k * 20 / d), -3)], k, 0, d - 1) → list5
  7. Sequence(Rectangle[20 / b, ((k * 20 / b), 2), ((k * 20 / b), 0)], k, 0, b - 1) → list1
  8. Sequence(Rectangle[20 / b, ((k * 20 / b), 2), ((k * 20 / b), 0)], k, 0, a - 1) → list2
  9. Sequence(Rectangle[20 / d, ((k * 20 / d), -1), ((k * 20 / d), -3)], k, 0, c - 1) → list3
  10. If((a * d) ≟ (b * c), "=", "≠") → Equal
