Graph on the Coordinate Plane
Name Period
Objectives / Objetivos
Content Objective: I can plot and identify points on the coordinate plane using ordered pairs.
Language Objective: I can explain my work using the words coordinate plane, ordered pair, origin, and quadrant.
Key Idea / Idea clave
Always start at the origin (0, 0), move right/left first, then up/down.
I Notice / Observo
- What shape will the three points make when connected?
- Which number tells you how far right/left? Which tells you up/down?
I Wonder / Me pregunto
- What if one of the coordinates was negative?

|---|---|
| Coordinate plane Plano cartesiano | A grid with a line going across and a line going up to plot points. Una cuadrícula con una línea horizontal y una vertical para marcar puntos. |
| Ordered pair Par ordenado | Two numbers (x, y) that tell where a point is on a grid. Dos números (x, y) que dicen dónde está un punto en una cuadrícula. |
| Origin Origen | The point (0, 0) where the two grid lines cross. El punto (0, 0) donde se cruzan las dos líneas de la cuadrícula. |
| Quadrant Cuadrante | One of the four parts of a coordinate grid, numbered I to IV. Una de las cuatro partes de una cuadrícula de coordenadas, numeradas I a IV. |
| Reflection Reflexión | A flipped, mirror image across a line. Una imagen reflejada al otro lado de una línea. |
| Integer Número entero | Whole numbers and their opposites, like -2, -1, 0, 1, 2. Números enteros y sus opuestos, como -2, -1, 0, 1, 2. |
Practice Preview / Vista previa de práctica
- Which ordered pair names a point 3 units right and 7 units up from the origin?
- (3, 7)
- (7, 3)
- (3, 3)
- (0, 7)
- Plot these points to reveal a hidden shape: (1, 1), (1, 5), (6, 5), (6, 1)
- Match each point to its quadrant or axis.
- Miscounted Grid Lines
- Step 1: Ordered pair — (7, 3)
- Step 2: Move along the x-axis — Start at the origin (0, 0) and count 7 units to the right.
- Step 3: Move along the y-axis — Count up from the x-axis: 1, 2, 3, 4 — stop on 4.
- Step 4: Plot the point — Place the dot at (7, 4).
Which step has the mistake? Explain it and write the correct work.
