This example demonstrates interactive fraction input and geometric transformations. It involves core math concepts like fraction operations, geometric translations, similar triangles, basic arithmetic, and fractal geometry. Construction highlights include using GeoGebra commands such as Textfield, Sequence, Element, Join, PolyLine for creating fraction inputs, sequence generation, and geometric sh

GeoGebra Commands & Parameters

  1. Textfield(input1) → InputBox1
  2. Sequence(Random[1, 10], i, 1, 10) → randomNumbers, {4, 10, 4, 9, 3, 8, 10, 7, 1, 6}
  3. Element(randomNumbers, Mod[questionCount, Length[randomNumbers]] + 1) → randomNumber
  4. Textfield(input) → inputBox
  5. Join({Sequence[Segment[Corner[4] + (RasterPixMat * ((k * RasterStepXY), 0)), Corner[4] + (RasterPixMat * ((k * RasterStepXY), RasterMaxY))], k, 0, RasterMaxX / RasterStepXY], Sequence[Segment[Corner[4] + (RasterPixMat * (0, (k * RasterStepXY))), Corner[4] + (RasterPixMat * (RasterMaxX, (k * RasterStepXY)))], k, 0, RasterMaxY / RasterStepXY]}) → RasterStrecken
  6. Join({Sequence[Text[UnicodeToLetter[65 + k], Midpoint[Corner[4] + (RasterPixMat * ((k * RasterStepXY), RasterMaxY)), Corner[4] + (RasterPixMat * (((k + 1) * RasterStepXY), RasterMaxY))], false, true, 0, -1], k, 0, RasterMaxX / RasterStepXY - 1], Sequence[Text[("" * k), Midpoint[Corner[4] + (RasterPixMat * (RasterMaxX, ((k - 1) * RasterStepXY))), Corner[4] + (RasterPixMat * (RasterMaxX, (k * RasterStepXY)))], false, true, 1, 0], k, 1, RasterMaxY / RasterStepXY]}) → RasterBeschriftung
  7. Sequence(Sequence[Corner[4] + (RasterPixMat * ((k * RasterStepXY), (m * RasterStepXY))), k, 0, RasterMaxX / RasterStepXY], m, 0, RasterMaxY / RasterStepXY) → RasterPunkte
  8. PolyLine(PosSB, Corner[txt012, 1] + (0.5, -0.25), Corner[txt012, 2] + (0.25, -0.25), Corner[txt012, 3] + (0.25, 0.25), Corner[txt012, 4] + (-0.25, 0.25), Corner[txt012, 1] + (-0.25, 0.25), PosSB) → sb01
