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.
WARM-UP
Practice without Coordinate Plane
1) How far apart are (- 2,6) and (5,6)? Is the line segment between the points horizontal or vertical?
2) How far apart are (3,5) and (3 ,- 7.5)? Is the line segment between the points horizontal or vertical?
3) How can you tell if the line segment between 2 points will be vertical or horizontal?

Practice with Coordinate Plane
MINI LESSON - INDEPENDENT WORK/SHARE OUT/DISCUSSION
1) Which number is closer to zero, -4/5 or 5/4?
2) Ms. Leopold is the chief of police in Baltimore, Maryland. Recently, Ms. Leopold began collecting data on the locations of crimes in Baltimore. She uses a computer program to plot each crime relative to the city center. This week, crimes occurred at (1,-5), (-2,-7) and (0,-6). Plot these crimes on a coordinate plane, and identify the quadrant of each crime. Where should Ms. Leopold station her police officers next week?

TEAM CHALLENGE
Archery
Mr. Hood is a young archer with a goal of qualifying for the Olympics. He has decided to track his improvement in accuracy by recording the placement of each arrow relative to the bullseye. In his most recent round, Mr. Hood's arrows stuck at (-4,1), (-2,-3), (4,-3) and (1,6). Plot Mr. Hood's arrows on the coordinate plane, and identify the quadrant of each arrow.
