This example demonstrates the process of adding integers using a number line. Key mathematical concepts include integers and their addition. It uses Vector and Segment objects in GeoGebra for construction. Suitable for high-grade elementary or junior high school students to learn integer addition.

GeoGebra Commands & Parameters

  1. Vector(A, B) → u
  2. Vector(C, D) → v
  3. Segment(Z, A) → g
  4. Segment(B, C) → h
  5. Segment(D, R) → i

AI Drawing Prompt Reference

Draw a horizontal number line in a coordinate system with marked origin and positive/negative integer ticks. Start from the origin, draw two directed line segments representing integer vectors. Connect the end of the first vector to the start of the second, and then connect the end of the second vector to a point on the number line to demonstrate the integer addition model.
The prompt above was compiled from the original drawing commands and is for reference only.
