This example demonstrates how to represent and compare fractions on a number line. The core math concepts involved include fractions, number line, absolute value, and coordinate system. Construction highlights the use of GeoGebra commands and objects like Point, Segment, Sequence to draw the number line, fraction points, and related segments. Suitable for middle school mathematics teaching, helping students understand the geometric meaning and representation of fractions on a number line.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Point(Circle[A, abs(Zoom)]) → C
  3. Segment(A, C) → b
  4. Sequence(((b / Nr * k), 0), k, 0, Nr) → list1
  5. Point(yAxis) → B
  6. Point(Circle[B, abs(Zoom)]) → D_1
  7. Segment(B, D_1) → c
  8. Sequence(((c / Nr * k), -1), k, 0, Nr) → list2
  9. Sequence(((c / ((Nr * Dr)) * k), -1), k, 0, (Nr * Dr)) → list4
  10. Sequence(((b / ((Nr * Dr)) * k), 0), k, 0, (Nr * Dr)) → list3
  11. Sequence(Segment[Element[list3, k], Element[list4, k]], k, 0, (Nr * Dr)) → list6
  12. Sequence(Segment[Element[list1, k], Element[list2, k]], k, 1, (Nr * Dr)) → list5
  13. Sequence(Text[k, ((b / Nr * k), (-1.5))], k, 1, Nr, 1) → list7
