概率统计几何作图函数图像
①本范例演示了基础图形绘制和数据可视化，适合小学阶段学生学习函数图像、随机数生成等概念；②涉及的核心数学概念包括函数图像绘制、随机数应用、数据排序与分类；③作图要点提炼自构造摘要，使用了Random, Shuffle, Intersect, Point, Textfield, Element, If, Sort等GeoGebra命令和对象；④适合小学低年级学生进行数学启蒙和图形认知教学。

GeoGebra 命令及参数

  1. Random(1, 5) → cats
  2. Random(1, 5) → dogs
  3. Random(1, 5) → horses
  4. Random(1, 5) → cows
  5. Shuffle({1, 2, 3, 4}) → CCDH
  6. Intersect(xAxis, yAxis) → A
  7. Point(xAxis) → B
  8. Point(xAxis) → C
  9. Point(xAxis) → D
  10. Point(xAxis) → E
  11. Textfield(inTxt) → inputBox1
  12. Shuffle({"cats", "cows", "dogs", "horses"}) → Alist
  13. Element(Alist, 1) → A1
  14. Element(Alist, 2) → A2
  15. If(A1 ≟ "cats", cats, If[A1 ≟ "cows", cows, If[A1 ≟ "dogs", dogs, horses]]) → ValueA1
  16. If(A2 ≟ "cats", cats, If[A2 ≟ "cows", cows, If[A2 ≟ "dogs", dogs, horses]]) → ValueA2
  17. Sort({cats, cows, dogs, horses}) → Order
  18. If(Element[Order, 4] ≟ cats, "cats", If[Element[Order, 4] ≟ cows, "cows", If[Element[Order, 4] ≟ dogs, "dogs", "horses"]]) → Most
  19. If(Element[Order, 1] ≟ cats, "cats", If[Element[Order, 1] ≟ cows, "cows", If[Element[Order, 1] ≟ dogs, "dogs", "horses"]]) → Least
