# Lesson 3

Ubiquemos más puntos

### Lesson Purpose

The purpose of this lesson is for students to plot points on the coordinate grid and recognize the importance of attending to precision when naming coordinates.

### Lesson Narrative

In previous lessons, students saw how coordinates are an effective tool for locating and describing points on the coordinate grid. In this lesson, they examine how points sharing the same vertical or horizontal coordinate are related. For example, the points $$(3,1)$$, $$(5,1)$$, and $$(6,1)$$ all have 1 as their second coordinate. Students see that they all lie on a horizontal line. Students study points that lie on the horizontal or vertical axes and see 0 as a possible value for a coordinate.
