Start hereWords, worked example, and sentence starters
Learning target With my small group, I can plot ordered pairs in all four quadrants of the coordinate plane — one step at a time, with support.
Start hereWords for this lesson
Read each word before you begin. Say it out loud.
| Word | What it means | Example |
|---|---|---|
| QuadrantSpanish: Cuadrante | One of the four parts of a coordinate grid, numbered I to IV. | I (+, +) top-right, II (-, +) top-left, III (-, -) bottom-left, IV (+, -) bottom-right |
| Negative coordinateSpanish: Coordenada negativa | A coordinate less than zero. It means left or below the center point. | (-3, 2) means 3 left and 2 up from the origin |
| ReflectionSpanish: Reflexión | A flipped, mirror image across a line. | (3, 2) reflected over the y-axis is (-3, 2) — same distance, opposite side |
| AxisSpanish: Eje | One of the two number lines that frame a graph: the x-axis runs across, the y-axis runs up and down. | The x-axis goes left-right; the y-axis goes up-down; they cross at (0, 0) |
| IntegerSpanish: Número entero | Whole numbers and their opposites, like -2, -1, 0, 1, 2. | ..., -3, -2, -1, 0, 1, 2, 3, ... |
How it worksWorked example
These numbers are not on your problems. The steps are. Follow them with your own numbers.
Plot the point (−3, −4). Name the quadrant it is in.
- Start at the origin: (0, 0)
- Read x. Move left 3 units: x = −3 → left 3
- Read y. Move down 4 units: y = −4 → down 4
- Use the signs to name the quadrant: (−, −) → Quadrant III
- (−3, −4) is in Quadrant III.
Now you trySame steps, your turn
The steps are the same as the worked example. The numbers are yours. Do the work.
Plot the point (−5, 2). Name the quadrant it is in.
Say it and write itSentence starters
Finish each sentence out loud with a partner. Then use them in your writing.
- In Quadrant , the x-coordinate is and the y-coordinate is . I know (-3, -4) is in Quadrant because both coordinates are .

Watch outA common mistake
A common mistake in Ordered Pairs in All Four Quadrants is matching each sign to the wrong axis — for example, seeing (-2, 5) and thinking "the x is negative so I move DOWN, and the y is positive so I move RIGHT," which lands the point in Quadrant IV. But the x-coordinate always controls left/right, never up/down: negative x means LEFT (not down), and positive y means UP (not right). So (-2, 5) is actually left 2, up 5 — Quadrant II. Before you submit, check that you used the x-coordinate for left/right and the y-coordinate for up/down, and never swapped them.

1Complete each step, then write the final answer.
Left 2, then down 5. Plot the point (−2, −5). Name the quadrant it is in.
- 1The x is −2. Which way do we move, and how far?
- 2The y is −5. Which way do we move, and how far?
- 3Left and down puts the point in which quadrant?
Final answer: -
2Complete each step, then write the final answer.
This time x is positive. Plot the point (3, −5). Name the quadrant it is in.
- 1The x is 3. Which way do we move, and how far?
- 2The y is −5. Which way do we move, and how far?
- 3Right and down puts the point in which quadrant?
Final answer: -
3Complete each step, then write the final answer.
Which quadrant is the point (−4, 1) in?
Show your workHint Negative x means move left. Positive y means move up.
Final answer: -
4Complete each step, then write the final answer.
Which quadrant is the point (−6, −2.5) in?
Show your workHint Look only at the signs. A decimal does not change the quadrant.
Final answer: -
5Complete each step, then write the final answer.
A ship is 4 units east and 3 units south of base camp at (0, 0). East is the positive x-direction. North is the positive y-direction. Which quadrant is the ship in?
Show your workHint Turn east and south into signs. South is the opposite of north.
Final answer: -
6Complete each step, then write the final answer.
Tia plots (2, −6) by moving up 2 and right 6. She says the point is in Quadrant I. What quadrant is (2, −6) really in?
Show your workHint Which number tells you to move left or right? Which tells you up or down?
Final answer:
Explain your thinkingTia used the numbers in the wrong order and ignored a sign. How do you plot an ordered pair the right way?
