NS.6b - Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.
WARM-UP
Name the Location
1) Where is (- 2, - 4 ) located? 2) Where is ( 0 , - 5 ) located?
3) Where is ( 6, 0 ) located? 4) Where is ( 4, - 4 ½) located?
3) Where is ( 6, 0 ) located? 4) Where is ( 4, - 4 ½) located?
Integers on the Coordinate Plane
MINI LESSON - INDEPENDENT WORK/SHARE OUT/DISCUSSION
What do you recognize when you plot these points on a coordinate plane?
- (3,4) and (-3,4)
- (2,-3) and (2,3)
TEAM CHALLENGE
Plot the following ordered pair and create a conjecture for how the locations of points can be determined by looking at the integer signs.
(-3,4) reflected over the x-axis; reflected over the y-axis
(-3,4) reflected over the x-axis; reflected over the y-axis
