Lesson objective: Find the distance between coordinates and from the coordinates to the x and y axis.

This lesson helps to build procedural skill with determining the distance between coordinates on a coordinate plane and from the coordinates to the x and y axis. A coordinate plane is used here because it is the tool on which students will find the distance between coordinates. This work develops students' understanding that we can locate and name points on a coordinate plane by identifying the x-coordinate and y-coordinate.

Students engage in Mathematical Practice 6 (Attend to precision) as they identify the exact coordinates of points plotted on a coordinate plane. Students must also take care when plotting points when given exact coordinates.

**Key vocabulary:**

- coordinate plane or grid
- x-axis
- y-axis
- x-coordinate
- y-coordinate
- ordered pair
- coordinates

**Special materials needed:**

- graph paper
- pre-printed coordinate grids
