Objectives Homework: SWBAT - Discuss the location of points and ordered pairs of given points Complete “He’s the King” worksheet Bell Ringer •5 minutes •4 minutes •3 minutes •2 minutes •1 minute •30 seconds •TIMES UP!!! Objectives SWBAT: Locate points in all four quadrants QUADRANTS Homework: Complete “He’s the King” worksheet 1. What is the difference between quadrant I and II? 2. What is the difference between quadrant IV and III Homework: Objectives Complete “He’s the King” worksheet SWBAT: Draw the coordinate plan and label all important aspects Quadrants THE X-AXIS AND Y-AXIS SEPARATE THE COORDINATE PLANE INTO FOUR REGIONS, CALLED QUADRANTS. II (-, +) I (+, +) III (-, -) IV (+, -) Objectives SWBAT: Locate points in all four quadrants NUMBER LINES: Homework: Complete “He’s the King” worksheet Breakthrough!!! Take a 2nd number line, standing it on its end, and cross the 1st number line at zero Objectives SWBAT: Locate points in all four quadrants AXES Number lines drawn like this are called “axes” (pronounced “ACK-seez”) – more than ONE axis x- axis: The horizontal number line y- axis: The vertical number line Objectives SWBAT: Locate points in all four quadrants COORDINATE PLANE Origin • Two number lines, or axes, one vertical & one horizontal, that intersect at their zero points, the origin. • A pair of numbers that correspond to the point where the two axes (number lines) cross each other origin (0,0) Objectives SWBAT: Locate points in all four quadrants x-coordinate: y-coordinate: Ordered Pair The first value in a coordinate pair. Indicates position on the x-axis The 2nd value in a coordinate pair. Indicates position on the y-axis Used to locate points on a coordinate plane 5 • 5 -5 -5 Objectives SWBAT: Locate points in all four quadrants Ordered Pair In an ordered pair, the first number is the x-coordinate and the 2nd number is the ycoordinate y-coordinate: EXAMPLE: GRAPH (-3, 2) 5 x-coordinate: • 5 -5 -5 NAME THE QUADRANT IN WHICH EACH POINT IS LOCATED (-5, 4) 1. 2. 3. 4. 5. 6. I II III IV None – x-axis None – y-axis NAME THE QUADRANT IN WHICH EACH POINT IS LOCATED (-2, -7) 1. 2. 3. 4. 5. 6. I II III IV None – x-axis None – y-axis NAME THE QUADRANT IN WHICH EACH POINT IS LOCATED (0, 3) 1. 2. 3. 4. 5. 6. I II III IV None – x-axis None – y-axis Objectives SWBAT: Draw the coordinate plan and label all important aspects Graphing Points To draw a dot at a point on the coordinate plane that Graph an Ordered Pair corresponds to an ordered pair. Also called: “Plotting a point” Steps to Graphing Step 1: Start at the origin Ordered Pairs Step 2: -If the x-coordinate is positive, move right the number of units indicated. -If the x-coordinate is negative, move left the number of units indicated Step 3: -If the y-coordinate is positive, move up the number of units indicated. -If the y-coordinate is negative, move down the number of units indicated Step 4: Draw a dot Step 5. Label the dot with the coordinate or letter given. Objectives SWBAT: Locate points in all four quadrants Plot each point on a coordinate plane • R(-4,1) • S(0, -3) • T(3, -2) Plotting “R” 1. Move left 4 units since the xcoordinate is -4 2. Move up 1 unit since the ycoordinate is 1 3. Draw a dot and label it R 5 • -5 • 5 -5 Objectives SWBAT: Locate points in all four quadrants Plot each point on a coordinate plane • • • • • • A(3, 5) B(0, -3) C(3, -2) D(0, -1) E(-2, 5) F(-3, -4) 5 -5 5 -5 Homework: OBJECTIVES SWBAT - DISCUSS THE LOCATION OF POINTS AND ORDERED PAIRS OF GIVEN POINTS DO NOW: 1. Label the Axes 2. Label each quadrant 3. Plot the following points ( 0,0) (1, 2) ( 2, 1) (5, 3) (2, 5) (-4, 3) (3, -4) (-1, -3) (-3, -1) Complete “He’s the King” worksheet Objectives Homework: SWBAT - Discuss the location of points and ordered pairs of given points Complete “He’s the King” worksheet Review Problems Objectives SWBAT - Discuss the location of points and ordered pairs of given points Reflection: Based on your knowledge of graphing and what we have done in class so far explain, in AT LEAST 4 complete sentences how, graphing can be used to in everyday life. Objectives SWBAT - Discuss the location of points and ordered pairs of given points Do Now: Start the “He’s the King” worksheet.
