This example demonstrates how to simplify fractions. The core mathematical concept involved is the simplification of fractions. Using GeoGebra commands such as Join, Element, and If, the process of fraction simplification is visually demonstrated. Suitable for students in grades 5-6.

GeoGebra Commands & Parameters

  1. Join({{4, 5}, Shuffle[Sequence[Random[2, 12], i, 1, 100]]}) → randomNosForZ
  2. Element(randomNosForZ, Mod[questionCount, 100]) → numZ
  3. Join({{2, 3}, Shuffle[Sequence[Random[1, 4], i, 1, 100]]}) → randomNosForX
  4. Join({{3, 4}, Shuffle[Sequence[Random[5, 9], i, 1, 100]]}) → randomNosForY
  5. If(questionCount ≟ 1, aInput ≟ 2, aInput ≟ numX / numZ) → correct1
  6. If(questionCount ≟ 1, bInput ≟ 3, bInput ≟ numY / numZ) → correct2
  7. Textfield(aInput) → InputBox1
  8. Textfield(bInput) → InputBox2
  9. Polygon(PtopLeftCornerFeedback, PtopRightCornerFeedback, PbottomRightCornerFeedback, PbottomLeftCornerFeedback) → rectangleCorrect, ptopleftcornerfeedback, ptoprightcornerfeedback, pbottomrightcornerfeedback, pbottomleftcornerfeedback
