This example demonstrates comparing fractions using number lines. Key mathematical concepts include fractions and their positions on the number line. It uses GeoGebra commands like Sequence, Point, and Segment for construction. Suitable for upper elementary or middle school students learning fraction comparison and number line representation.

GeoGebra Commands & Parameters

  1. Sequence(Point[{i / d2, a}], i, 0, d2) → l1
  2. Point(l1) → A
  3. Segment((0, a), (1, a)) → f
  4. Sequence(Point[{i / d1, 2 - a}], i, 0, d1) → l2
  5. Segment((0, 2 - a), (1, 2 - a)) → g
  6. Point(l2) → B
  7. Zip(Segment[AAA - (0, segmentSize), AAA + (0, segmentSize)], AAA, l1) → l3
  8. Zip(Segment[AAA - (0, segmentSize), AAA + (0, segmentSize)], AAA, l2) → l4
