本范例演示了如何判断一个数是否为3的倍数。核心数学概念包括数感、因数与倍数。通过使用GeoGebra命令如Textfield、Shuffle等,学生可以互动地探索和验证3的倍数规则。适合小学5-6年级学生学习。

GeoGebra 命令及参数

  1. Textfield(input1) → InputBox1
  2. Textfield(input2) → InputBox2
  3. Shuffle(1…9) → Num1List, {9, 5, 6, 3, 8, 7, 2, 4, 1}
  4. Shuffle(0…9) → Num2List, {7, 4, 8, 9, 6, 1, 0, 2, 3, 5}
  5. Shuffle(0…9) → Num3List, {8, 4, 0, 5, 7, 6, 9, 3, 2, 1}
  6. Shuffle(0…9) → Num4List, {4, 7, 9, 8, 1, 6, 3, 0, 2, 5}
  7. Shuffle(1…4) → exList, {4, 1, 2, 3}
  8. Polygon(PtopLeftCornerFeedback, PtopRightCornerFeedback, PbottomRightCornerFeedback, PbottomLeftCornerFeedback) → rectangleCorrect, rectangleCorrectS3, rectangleCorrectS4, rectangleCorrectS2, rectangleCorrectS1
  9. Shuffle(Sequence[Random[0, 10], i, 1, 100]) → randomNosForX, {6, 3, 7, 4, 8, 4, 3, 6, 3, 1, 1, 10, 1, 9, 9, 4, 3, 1, 10, 5, 5, 4, 5, 8, 3, 3, 3, 1, 6, 9, 7, 9, 0, 0, 1, 1, 9, 6, 8, 1, 3, 4, 7, 8, 0, 9, 9, 3, 1, 10, 6, 5, 6, 9, 7, 6, 0, 0, 6, 5, 4, 9, 3, 4, 7, 0, 3, 4, 6, 6, 3, 0, 3, 2, 2, 7, 5, 5, 3, 9, 0, 3, 8, 6, 6, 9, 8, 5, 3, 7, 9, 6, 9, 10, 0, 3, 5, 8, 2, 6}
  10. Element(randomNosForX, Mod[questionCount, 100] + 1) → numX

AI 绘图提示语参考

创建一个交互式图形,展示数字3的整除性。包含输入框供用户输入数字,并显示1-9和0-9的随机排列。用不同颜色标记随机生成的数字对,并绘制一个由四个点组成的矩形。根据输入数字的各位数之和是否为3的倍数,用语音气泡提示结果。
