This example demonstrates how to represent and visualize rational numbers on a number line. Core math concepts include rational numbers, number line, and fractional representation. It uses GeoGebra commands like Sequence and Segment. Suitable for middle school and above to learn rational number concepts and number line representation, or for mathematical teaching demonstrations.

GeoGebra Commands & Parameters

  1. Sequence(RandomElement[dens], i, 1, 5) → list6_1
  2. Sequence(Random[(-2 * Element[list6_1, i]), (2 * Element[list6_1, i])], i, 1, 5) → list7_1
  3. Sequence(Element[list7, i] / Element[list6, i], i, 1, 5) → flist
  4. Sequence((-x(Element[list8, i])) + Element[flist, i] > error, i, 1, 5) → toosmall
  5. Sequence(x(Element[list8, i]) - Element[flist, i] > error, i, 1, 5) → toobig
  6. Segment(A, B) → f_1
  7. Sequence(Segment[(-2 + i, -0.12), (-2 + i, 0.12)], i, 0, 4, 1) → list1
  8. Sequence(Text[-2 + i, (x(C) + (1.02 * i), y(C))], i, 0, 4) → list2
  9. Sequence(Segment[(-2 + i, -0.11), (-2 + i, 0.11)], i, 0, 4, 0.5) → list3
  10. Sequence(Segment[(-2 + i, -0.09), (-2 + i, 0.09)], i, 0, 4, 0.25) → list4
  11. Sequence(Segment[(-2 + i, -0.07), (-2 + i, 0.07)], i, 0, 4, 0.125) → list5
