standard_description: Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.
problem_activity: Label the second quadrant on the coordinate plane, and then answer the following questions.
[IMG]
a.   Write the coordinates of one point that lies in the second quadrant of the coordinate plane.
b.    What must be true about the coordinates of any point that lies in the second quadrant?
c.    Plot and label the following points:
$${A: (-4, 6)}$$
$${B: (6, -4)}$$
$${C: (0, -2)}$$
$${D: (2, 0)}$$
$${E: (-5, -3)}$$
