This example demonstrates how to construct a number line and related elements using GeoGebra. Core math concepts include number lines, coordinates, and geometric transformations. Key GeoGebra commands used are Sequence for ticks, Segment for lines, Textfield for labels, Ellipse, and Corner for corner connections. Suitable for middle school and above, teaching number line operations, equation solving, and function graphing.

  10. Textfield(text7) → Label7
  11. Textfield(text8) → Label8
  12. Textfield(text9) → Label9
  13. Textfield(text0) → Label0
  14. Ellipse((-0.2, 0), (0.2, 0), 0.25) → c
  15. Corner(1) → A
  16. Corner(3) → C
  17. Segment((x(A), -0.5), (x(C), -0.5)) → align2
  18. Segment((x(A), 1.25), (x(C), 1.25)) → align1

AI Drawing Prompt Reference

Draw a horizontal number line extending from -100 to 100 on the x-axis. Generate tick marks at every integer unit from -50 to 50, both above and below the line. Place ten text boxes below the number line, labeled with digits 0 through 9, arranged in a row. Near the origin, draw a small flattened ellipse as a marker on the line. Add two horizontal alignment guides: one below the number line at y = -0.5 and one above at y = 1.25, both spanning the same width as the number line. Ensure the layout clearly shows the number line, ticks, text boxes, and guides in relation to each other.
