FunctionSequenceGeometric Construction
This example uses GeoGebra to demonstrate the concept of addition. It involves the core mathematical concept of addition. Using commands such as Sequence, Vector, OrthogonalLine, and Segment, a geometric model of addition is constructed. Suitable for high-grade elementary or junior high school students to learn addition.

GeoGebra Commands & Parameters

  1. Sequence(Segment[(i, 2.2), (i, 1.8)], i, -20, 20) → L_1
  2. Sequence(Segment[(i, -2.2), (i, -1.8)], i, -20, 20) → L_2
  3. Sequence(Text[i, (i - 0.3, -0.2)], i, -20, 20, 5) → L_3
  4. Sequence(Segment[(i, 2.5), (i, 1.5)], i, -20, 20, 5) → L_4
  5. Sequence(Segment[(i, -2.5), (i, -1.5)], i, -20, 20, 5) → L_5
  6. Vector(A, B) → u
  7. Vector(D, C) → v
  8. OrthogonalLine(C, xAxis) → h
  9. Vector(E, F) → w
  10. Vector(G, H) → a
  11. Segment(D, B) → i
  12. Segment(F, G) → j

AI Drawing Prompt Reference

Draw an addition model with 20 vertical segments from -20 to 20 at y=2.2, y=-2.2, y=2.5, and y=-2.5. Mark numbers -20 to 20 on the x-axis. Draw two vectors u and v from point A to B and point D to C. Draw a vertical line h through point C. Draw two vectors w and a from point E to F and point G to H. Draw line segments DB and FG.
