本范例通过让用户统计Florian拥有的袜子数量，练习绝对频率的统计方法。核心数学概念是绝对频率（absolute frequency）的概念与计数方法。从构造摘要可见，该练习使用了Textfield文本框、Polygon多边形、Shuffle随机排列命令，配合count计数、InputBox输入框及btnValidate验证按钮，实现交互式统计练习。学生可在输入答案后点击验证按钮，系统会判断答案是否正确并给出反馈。适合德国或采用类似学制的5-6年级学生使用，也可作为数学启蒙阶段练习计数与统计的入门素材。

AI 绘图提示语参考

绘制一个坐标系，其中包含10个点，这些点的坐标随机分布在一个矩形区域内。学生需要通过计数每个点的数量来练习绝对频率的概念，即每个点出现的次数。首先绘制一个矩形区域，然后随机生成10个点并显示在区域内，最后让学生输入他们认为每个点的数量，并通过验证按钮检查答案。
