Graph on the Coordinate Plane

Lost Cove Mission

Captain Vega's Coordinates

You are the navigator on Captain Vega's expedition. Instead of 'X marks the spot,' she hid the treasure route as ordered pairs scrawled across the first quadrant of her chart, using only positive coordinates. Plot every point in the right order and the lost cove treasure is yours.

1. Understand the Question

explain

Your map says the treasure is at (4, 2). Walk your partner through every move you make from the origin, using the words x-axis and y-axis?

Your job: Answer the question. Use math evidence. Explain how the evidence proves your answer.Responde la pregunta. Usa evidencia matemática. Explica cómo la evidencia demuestra tu respuesta.

2. Plan Your Math Words

Check at least two words you will use.

Coordinate plane — A grid with a line going across and a line going up that cross.Plano cartesiano — Una cuadrícula con una línea horizontal y una vertical que se cruzan. Ordered pair — Two numbers (x, y) that tell where a point is on a grid.Par ordenado — Dos números (x, y) que dicen dónde está un punto en una cuadrícula. Origin — The point (0, 0) where the two grid lines cross.Origen — El punto (0, 0) donde se cruzan las dos líneas de la cuadrícula. Quadrant — One of the four parts of a coordinate grid.Cuadrante — Una de las cuatro partes de una cuadrícula de coordenadas. Reflection — A flipped, mirror image across a line.Reflexión — Una imagen reflejada al otro lado de una línea.

Say it first: Say your idea to a partner or quietly to yourself before you write.Di tu idea a un compañero o en voz baja antes de escribir.

I move ___ units along the x-axis.Me muevo ___ unidades por el eje x.

3. Build Your Explanation

Model the parts: This model shows the parts of an explanation. It does not answer your writing question.

Claim: We start at the origin and move along the x-axis first because ___.

Evidence: Student states the x-coordinate is the sideways move and the y-coordinate is the up/down move, both starting from the origin.

Reasoning: This evidence connects the definition of coordinate plane to the mathematical claim.
