时区与整数比较
几何画板及绘图内容加载中,请稍等……
本范例通过多个选择题和开放题,帮助学生理解时区的概念及其与整数的关系。涉及的核心数学概念包括整数的比较和排序,以及在实际生活中的应用。使用了GeoGebra中的Sequence, Element, Textfield, Circle等命令进行图形构造。适合5-6年级的学生学习。

AI 绘图提示语参考
绘制一个展示不同城市时区整数比较的图形。图中包含多个圆形标记,代表不同城市,每个圆形旁有文本框显示对应的整数时间差,例如-7、-6等。图形中还画有一个飞机的标记,表示飞行路径。构造顺序为:先绘制所有圆形,再添加文本框,最后添加飞机标记。图形适合5-6年级学生理解整数比较与时区关系。
