解析几何几何作图
该范例通过熊赛跑的游戏情境，演示了加减法的概念。它涉及的核心数学概念包括加法和减法。通过使用GeoGebra命令如Point、Element、Sequence等，构建了一个动态的加减法练习环境。适合小学高年级或初中低年级学生进行加减法的练习和理解。

AI 绘图提示语参考

绘制一个以赛跑为主题的数学游戏场景。画面中有两条平行的水平数轴，每条数轴上标有从0到10的刻度点，并配有数字标签。数轴两端各有一个彩色矩形区域作为终点区。每条数轴上有一个可移动的圆点代表玩家，下方各有一只小熊图标作为对手。画面中央有一个圆形转盘，被六等分，每份扇形内标有加减运算符号和数字（如+0、+1、+2等），转盘中心有指针。转盘旁有一个计分表格，显示正确与错误次数。整体布局清晰，适合教学演示。
