Lesson Purpose

In this lesson, students will learn the basic knowledge or a coordinate grid and what it is useful.  Students will learn to plot points and use points to determine location.  Knowledge of the coordinate plane is a precursor to more advanced geometry and trigonometry.  In and of itself, however, the application of some sort of organized locator plan is used in groceries, department stores, parking lots, campuses of colleges and large businesses, and, locally, in at least four factories.

Lesson Objectives

At the end of this lesson, students will be able to:

• demonstrate correct use of key vocabulary
• graph points in all four quadrants of the coordinate plane
• determine the distance between points by applying knowledge of absolute value.

Student Target

"I can

• graph points in all four quadrants of the coordinate plane."
• determine the distance between points on a coordinate plane."

CCR Focus Standards

Geometry - Level C

• 5.G.1

  Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., x-axis and x-coordinate, y-axis and y-coordinate).

• 5.G.2

  Represent real world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation.

Number and Ratios - Level D

Supporting Standards

• 6.NS.6c

  Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane.
  

• 6.NS.8

  Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate.
  

• W/WHST.6-8.2

  Write informative/explanatory texts to examine a topic and convey ideas, concepts, and information through the selection, organization, and analysis of relevant content. [This includes the narration of historical events, scientific procedures/experiments, or technical processes.]

  a. Introduce a topic clearly, previewing what is to follow; organize ideas, concepts, and information, using strategies such as definition, classification, comparison/contrast, and cause/effect; include formatting (e.g., headings), graphics (e.g., charts, tables), and multimedia when useful to aiding comprehension. 

  b. Develop the topic with relevant facts, definitions, concrete details, quotations, or other information and examples. 

  c. Use appropriate transitions to create cohesion and clarify the relationships among ideas and concepts. 

  d. Use precise language and domain-specific vocabulary to inform about or explain the topic. 

  e. Establish and maintain a formal style. 

  f. Provide a concluding statement or section that follows from and supports the information or explanation presented.
