这个范例演示了如何通过平均分派来分享数粒。核心数学概念包括平均数和分派。使用了命令如 Textfield, Div, Mod, Sequence, Polygon 等来构造图形。适合小学高年级或初中学生学习。

GeoGebra 命令及参数

Textfield(divid) → InputBox1Divid
Textfield(div) → InputBox2Div
Div(divid, div) → Qu
Mod(divid, div) → Re
Sequence(Polygon[Co + (0, ((BoxHeight + BoxSpacing) * k)), Co + (0, ((BoxHeight + BoxSpacing) * k) + BoxHeight), Co + (BoxWidth, ((BoxHeight + BoxSpacing) * k) + BoxHeight), Co + (BoxWidth, ((BoxHeight + BoxSpacing) * k))], k, 0, div - 1) → listBox, {67.5, 67.5, 67.5, 67.50000000000011}
Polygon(RegCo1, RegCo2, RegCo3, RegCo4) → RegionOne, RegOneS1, RegOneS2, RegOneS3, RegOneS4
If(ShowChi, "中文", "Eng") → TextLanguage
If(ShowChi, "顯示答案", "Show Answer") → TextAns
If(ShowChi, "計算新一題前，先按上方的重置按鈕。", "Press the button above for resetting.") → TextReset
If(ShowChi, "可顯示1至30粒數粒，及1至9個盒。", "It can display 1 to 30 squares, and 1 to 9 boxes.") → Text5
