SequenceCoordinate GeometryGeometric Construction
This example uses a number line to help students find equivalent fractions and reinforce the same position on the number line. It demonstrates the properties of equivalent fractions and involves core fraction concepts. It uses GeoGebra commands such as Sequence, Segment, Element, and Vector, suitable for upper elementary or middle school students.

GeoGebra Commands & Parameters

  1. Sequence((x(A) + i * l / d1, y(A)), i, 0, d1) → top1
  2. Sequence((x(A) + i * l / d1, y(A) - yb), i, 0, d1) → bot1
  3. Sequence(Segment[Element[bot1, j], Element[top1, j]], j, 1, d1 + 1) → seg1
  4. Segment(C, D) → a
  5. Sequence((x(A) + i * l / d2, y(A) + yb), i, 0, d2) → top2
  6. Sequence((x(A) + i * l / d2, y(A)), i, 0, d2) → bot2
  7. Sequence(Segment[Element[bot2, j], Element[top2, j]], j, 1, d2 + 1) → seg2
  8. Segment(E, F) → b
  9. Segment(G, H) → c
  10. Element(bot1, n1 + 1) → S
  11. Element(top2, n2 + 1) → Q
  12. Vector(R, Q) → u
  13. Vector(T, S) → v

AI Drawing Prompt Reference

Draw two parts on a horizontal line, each consisting of multiple consecutive line segments. One part rises gradually from left to right at the top of the line, while the other part falls gradually from left to right at the bottom, connected by vertical line segments. Then, draw two separate line segments to the right of the upper and lower parts. Finally, draw one vector from a point on the lower part to a point on the upper part to the right and above, and another vector from a point on the upper part to a point on the lower part to the right and below.
