在第一象限中描点
Plotting points in the first quadrant
在坐标平面的第一象限中标出并读取有序数对；通过描点来表示现实生活和数学问题，并结合具体情境解释坐标值的含义。
Plot and read ordered pairs in the first quadrant of the coordinate plane; represent real-world and mathematical problems by graphing points and interpreting coordinate values in context
学习证据 / Evidence
- 在第一象限的网格上准确标出点（4, 7）
- 在坐标平面上以点的形式绘制一组数据对（例如时间与距离）
- 读取已绘制的点的坐标，并解释它们在给定情境中的含义
- Plot the point (4, 7) accurately on a first-quadrant grid
- Graph a set of data pairs (e.g. time vs distance) as points on the coordinate plane
- Read coordinates of a plotted point and explain what they represent in a given scenario
评估问题 / Assessment
如果告诉{{name}}，一辆汽车在地图上的行程经过格点（2, 3）、（5, 7）和（8, 4），{{name}}能否标出这些点并描述这段行程是什么样的？
If you tell {{name}} a car journey passes through grid points (2, 3), (5, 7), and (8, 4) on a map, can they plot those points and describe what the journey looks like?
