# Lesson 2

Puntos en la cuadrícula de coordenadas

### Lesson Purpose

The purpose of this lesson is for students to locate and describe points on the coordinate grid.

### Lesson Narrative

In this lesson students use the numbers on the horizontal and vertical axes to describe the location of points in the plane and then learn that these numbers are called the

**coordinates**of points. They learn that the point \((5,2)\), for example, is on the vertical line labeled 5 and the horizontal line labeled 2. The number 5 is called the horizontal coordinate of \((5,2)\) and the number 2 is called its vertical coordinate. Students practice identifying the coordinates of points and plot points with given coordinates. It gives students a reason to attend to the location and coordinates of each point and to use language precisely to describe them (MP6).- Representation
