"Navigating the Coordinate Plane"
In a storm, a sailor needs a fixed point to know where he is. Without a map and a compass, he is lost. In mathematics, the Coordinate Plane is our map. The axes are our compass. The Origin $(0,0)$ is our home.
Every point on the grid has a name and a place. Nothing is hidden; everything is located relative to the Center. As you learn to plot points, remember that you are learning the art of Divine Order. God is not a God of confusion, but of peace (1 Cor 14:33).
On the grid below, mark the following:
Why do we call $(0,0)$ the "Origin"? If you start a race, what mile marker are you at before you take a step?
Coordinates of Home: ( , )If you run Right 5 but do NOT jump up or down, where are you?
Address: ( , )If X is Negative and Y is Positive, I am in Quadrant .
If X is Positive and Y is Negative, I am in Quadrant .
If X is Negative and Y is Negative, I am in the Deep Water (Quadrant ).
Plot these points and connect them in order:
(0, 4) $\rightarrow$ (3, 0) $\rightarrow$ (-3, 0) $\rightarrow$ (0, 4)
What shape did you build?
Plot these points:
(2, 2) $\rightarrow$ (2, -2) $\rightarrow$ (-2, -2) $\rightarrow$ (-2, 2) $\rightarrow$ (2, 2)
Is the Origin inside the square?
Identify the location (Quadrant or Axis) for each point. Write Q1, Q2, Q3, Q4, X-Axis, or Y-Axis.

Before you learned the grid, points were just floating in space. Now, every point has an address. It has a relationship to the Origin.
Reflect: How does it feel to know that you can describe exactly where something is? Does the grid make the world feel smaller or bigger? Organized or messy?
A student claims: "The point $(0, 5)$ is on the X-Axis because it has a zero."
Is this the Truth? Plot the point $(0, 5)$ in your mind. Did you move Right/Left? Or did you move Up/Down? Correct the student's error.
Verdict:
"I, a Navigator of the Map of Truth, promise to follow the directions of the Great Architect. I will run before I jump, starting at the Origin of all things. I will respect the boundaries of the Quadrants and the law of the Axes. I am located in Truth."
