This example demonstrates interactive self-assessment for solving simple inequalities. Key math concepts include inequalities and algebra. It is constructed using GeoGebra commands like If, Random, RandomElement, Textfield, Segment, Sequence, and objects such as useranswerineq, useransval, usergreaterthan, etc. Suitable for middle school and above, for practice and self-evaluation.

GeoGebra Commands & Parameters

  1. If(userincludepoint, If[usergreaterthan, 4, 3], If[usergreaterthan, 2, 1]) → userIneqIndexNum
  2. Random(1, 4) → SelectedIneqListIndexNum
  3. RandomElement({1, 2, 1, 3, 1, 5, 1}) → ansvaldenom
  4. Random(-5, 7) → ansvalnum
  5. Textfield(a) → Inequality
  6. Segment((x(P_{arrowright}), -0.5), (x(Corner[2]), -0.5)) → xAxis_{continuation}
  7. Sequence(Text[i, (i - ticksize / 5, -3)], i, xLeft + 1, xRight - 1, ticksize) → ListxaxisNumbers
  8. Sequence((i, -0.6), i, xLeft, xRight, 1) → listTicks
  9. If(SelectedIndex[typeinequalitylist] ≟ 1 ∨ SelectedIndex[typeinequalitylist] ≟ 3, true, false) → arrowleft
  10. If(SelectedIndex[typeinequalitylist] ≟ 2 ∨ SelectedIndex[typeinequalitylist] ≟ 4, true, false) → arrowright
  11. If(useransval ≟ answervalue ∧ userIneqIndexNum ≟ SelectedIneqListIndexNum, true, false) → answercorrect
  12. RandomElement({-3, -2, -1, 2, 3, 4, 5}) → factora
  13. Textfield(useranswerineq) → InputBox1
  14. If(factora < 0, If[SelectedIneqListIndexNum < 2, 2, If[SelectedIneqListIndexNum > 3, 3, If[SelectedIneqListIndexNum < 3, 1, 4]]], SelectedIneqListIndexNum) → DisplayIneqListIndexNum

AI Drawing Prompt Reference

Create an interactive inequality solving exercise with a coordinate axis, inequality symbols, and color-coded correct answers based on user input. Include arrows on the left and right sides, number ticks at the top, and a text box for user input showing the inequality and solution status.
