Students fix three axis and plotting errors — moving up before right, horizontal axis called y-axis, and (0,4) plotted to the right. Part B has four questions about axis names and plotting steps. Part C has two questions about plotting steps for (6,4) and what shared x-coordinates reveal.
Correcting axis and plotting direction errors ensures that students build correct mental models of the coordinate grid before using it for measurement, shapes, or patterns.

Coordinate Plane
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
To plot (5, 3), start at the origin and move 5 units up, then 3 units right.
Rewrite: To plot (5, 3), start at the origin and move 5 units right, then 3 units up.
2. Fix the sentence:
The horizontal axis on a coordinate plane is called the y-axis.
Rewrite: The horizontal axis on a coordinate plane is called the x-axis.
3. Fix the sentence:
The point (0, 4) is plotted 4 units to the right of the origin.
Rewrite: The point (0, 4) is plotted 4 units up from the origin.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The horizontal axis is called the x-axis.
2. The vertical axis is called the y-axis.
3. To plot (3, 7), move 3 units right from the origin.
4. To plot (3, 7), move 7 units up from the origin.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Describe the steps to plot the point (6, 4) on a coordinate plane.
Start at the origin (0, 0). Move 6 units right along the x-axis. Then move 4 units up parallel to the y-axis. Mark and label the point (6, 4) at that location.
2. Two points are plotted: P at (2, 5) and Q at (2, 1). What do you notice about their x-coordinates and what does that tell you about their positions?
Both points have the same x-coordinate of 2, so they are both 2 units right of the origin. They lie on the same vertical line. Point P is higher on the grid than Point Q.

Rewrite: To plot (5, 3), start at the origin and move 5 units right, then 3 units up.
2) Fix the sentence:
The horizontal axis on a coordinate plane is called the y-axis.
Rewrite: The horizontal axis on a coordinate plane is called the x-axis.
3) Fix the sentence:
The point (0, 4) is plotted 4 units to the right of the origin.
Rewrite: The point (0, 4) is plotted 4 units up from the origin.
