This example demonstrates the concept of percentage change, involving core mathematical concepts such as ratios and rates. Using GeoGebra commands like Sequence, Union, RandomElement, etc., it dynamically illustrates percentage changes in various scenarios. Suitable for middle school and above students to learn about ratios and rates.

GeoGebra Commands & Parameters

  1. Sequence(i, i, 4, 98, 4) → list2
  2. Sequence(i, i, 5, 95, 5) → list1
  3. Union(list1, list2) → list3
  4. RandomElement(list3) → p
  5. RandomElement({-1, 1}) → s
  6. RandomElement(list4) → var
  7. If(s ≟ 1, "+", "-") → textS
  8. If(s ≟ 1, "-", "+") → textS'
  9. If(qtype ≟ 1, textMultiCorrect, If[qtype ≟ 2, textDivCorrect, textPercent1]) → textCorrect
  10. If(qtype ≟ 1, textMultiWrong, If[qtype ≟ 2, textDivWrong, textPercent2]) → textWrong1
  11. If(qtype ≟ 1, textDivCorrect, If[qtype ≟ 2, textMultiCorrect, textPercent3]) → textWrong2
  12. If(qtype ≟ 1, textDivWrong, If[qtype ≟ 2, textMultiWrong, textPercent4]) → textWrong3
  13. Shuffle({(0, 0), (10, 0), (0, -4), (10, -4)}) → listPos
