options: Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates.

Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate.

Understand ordering and absolute value of rational numbers.

Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.
problem_activity: Problem 1
Consider the set of numbers
$$6$$
,
$${4 \frac{1}{2}}$$
,
$$2$$
, and
$$5$$
, and answer the questions that follow.
a.   Graph the numbers on the number line and list the numbers in order from least to greatest.
[IMG]
b.   Write the opposites of each number and graph them on the number line.
c.   Order the opposites from least to greatest.
d.   Is −5 greater than −2? Explain using your number line.
Problem 2
Order the rational numbers below from least to greatest.
$${5, -4, -\frac{1}{3}, \frac{10}{3}, 3, 0, -4\frac{1}{4}, -4\frac{3}{4}}$$
What strategies did you use to determine the correct order?
Problem 3
A student orders three rational numbers from least to greatest as:
$${{{{{{{{{-5}}}}}}}}}$$
,
$${{{{{{{{{-5}}}}}}}}} \frac {1}{3}$$
,
$$6$$
