10/5 Bell Ringer Step 1: Grab todays materials from the front of the room Step 2: On your bell ringer sheet, set up a coordinate plane (see example), label the x and y-axes and then plot these three points: (2,6) (4,1) and (3,2). Homework: Finish Independent Practice on Coordinate Plane navigation.
10/5 News and Notes Did you reach your goal? Are you Raising the Bar? Schedule for week: –Today: Coordinate plane review –Tom: Reflections in coordinate plane –Thurs & Fri: Translations and Rotations in coordinate plane –Mon: No School –Tues: Review –Wed: Test
10/5 Agenda I CAN identify, navigate and plot points in all four quadrants of the coordinate plane. 1.Bell Ringer 2.New Material – Examples 3.Connect the Dots 4.Independent Practice 5.ACT Question of the Day
Bell Ringer Review / Intro to New Material X Y Recall that all points are in the form (x,y). This is called an ordered pair. (2,6) (4,1) (3,2) (2,6) (4,1) (3,2)
Intro to New Material X Y All of the points were in the first quadrant. What are the other 3 quadrants? What happens when we make X negative? (-2,6) (-4,1) (-3,2) (-2,6) (-4,1) (-3,2) III IVIII
Intro to New Material X Y What happens when we make Y negative? (2,-6) (4,-1) (3,-2) (2,-6) (4,-1) (3,-2) III IVIII
Intro to New Material X Y What happens when we make X and Y negative? (-2,-6) (-4,-1) (-3,-2) (-2,-6) (-4,-1) (-3,-2) III IVIII
Now make a general conclusion. What will be true of x and y in each quadrant? Q1: (x, y) Q2: (-x, y) Q3: (-x, -y) Q4: (x, -y) X Y I (+,+)II ( –, +) IV (+, –) III (–, –)
Connect the Dots Each column will create a graph. Heres the process: Round 1: Plot & label given point; Pass back. Round 2: Check previous, plot new point; Pass. Round 3: Same as 2 … Round 6: Check all, connect dots, pass.
Independent Practice You now have all but the last 5 minutes for the Independent Practice
ACT Question of the Day Given points (5,3), (3, -2) and (1,9), which quadrants are empty? A.I and II B.II and III C.III and IV D.I and IV E.II and IV Homework: Finish Independent Practice on Coordinate Plane navigation.
