分数运算练习 - 四则运算结合
几何画板及绘图内容加载中,请稍等……
本范例通过选择分数气泡来练习四则运算。涉及的核心数学概念包括括号和运算优先级规则,以及四则运算的结合应用。构造摘要中使用了Join, Spline, Textfield, Polygon等GeoGebra命令。适合5-6年级学生使用。

AI 绘图提示语参考
在坐标平面上构造一个用于分数运算练习的组合算术示意图:先生成一组用于连线的样条路径控制点,并用三条样条分别形成三段弯曲的边界效果,同时在中间配套生成用于排版的文本输入框。再在一个矩形区域内放置四个角点对应的分区轮廓,画出正确的矩形边界。最后在图中加入若干文本框位置,用于承接分数运算相关的输入内容,并确保整体为可交互的练习版面。
