Session Objectives
• Examine the development of mathematical
understanding across the module using a focus on
concept development within the lessons.
• Identify the big idea within each topic in order to
support instructional choices that achieve the lesson
objectives while maintaining rigor within the
curriculum.

Module’s Foundation
• Standards: 6.NS.C.5, 6.NS.C.6, 6.NS.C.7, 6.NS.C.8
• Pages 7 – 8 in the Progressions Document (The Number System, 6-8) serves
as a foundation.
• Directed measurement --- a rational number’s position on the number line
is found using length and direction.
• The opposite of a number a, is –a. Both a and –a are located an equal
distance from zero, in opposite directions.
• Rational numbers represent real-world situations.

Positive and Negative Numbers on the Number
Line: Opposite Direction and Value
Outcomes:
• Students extend their understanding of the number line,
which includes zero and numbers to the right, that are
above zero, and numbers to the left, that are below zero.
• Students use positive integers to locate negative
integers, moving in the opposite direction from zero.
• Students understand that the set of integers is the set of
whole numbers and their opposites, and understand that
zero is its own opposite.

Positive and Negative Numbers on the Number Line:
Opposite Direction and Value
• The number line extends to include negative numbers.
• Lengths on the right-side and left-side of zero are the same for a
number and its opposite. (Use a compass for the construction.)
• The set of whole numbers and their opposites
(zero is its own opposite) are called integers.
• The order of the set of integers is: …-5,-4,-3,-2,-1,0,1,2,3,4,5…

Positive and Negative Numbers on the Number Line: Opposite
Direction and Value
• Draw a horizontal line. Place a point on the line and label it 0.
• Use a compass to locate and label the next point 1, thus creating a scale.
(Continue to locate other whole numbers to the right of zero using the
same unit measure.)
• Using the same process, locate the opposite of each number on the left
side of zero. Label the first point to the left of zero, -1.

Real World Positive and Negative Numbers and
Zero
Outcomes:
• Students use positive and negative numbers to indicate a change
(gain or loss) in elevation with a fixed reference point, temperature,
and the balance in a bank account.
•
Students use vocabulary precisely when describing and
representing situations involving integers; for instance, an elevation
of −10 feet is the same as 10 feet below the fixed reference point.
•
Students will choose an appropriate scale for the number line when
given a set of positive and negative numbers to graph.

Real World Positive and Negative Numbers and Zero
• Use positive and negative numbers and zero to represent
situations.
• Graph integers on a number line, using an appropriate
scale and relating points to real-world situations.
• Explain the meaning of zero in the context of a situation.

The Opposite of a Number’s Opposite
Outcomes:
• Students understand that, for instance, the opposite
of −5 is denoted −(−5) and is equal to 5. In
general, they know that the opposite of the opposite
is the original number; e.g., −(−) = .
• Students locate and position opposite numbers on a
number line.

Ordering Integers and Other Rational Numbers
Outcomes:
• Students write, interpret, and explain statements of
order for rational numbers in real world contexts.
• Students recognize that if a < b, then -a > -b, because
a number and its opposite are equal distances from
zero; and moving along the horizontal number line to
the right means the numbers are increasing.

Ordering Integers and Other Rational Numbers
What is the Value of Each Number and Which is Larger?
1) The first number is 8 ½ units to the right of -5. The second number is 3
units to the right of 0.
First Number: 3.5; Second Number: 3; 3.5 is larger than 3.
2) The first number is ¼ unit to the left of -7.
The second number is 8 units to the left of 1.
First Number: −7.25; Second Number: −7; −7 is larger than −7.25.
3) The opposite of the first number is 2 units to the right of 3.
The opposite of the second number is 2 units to the left of -3.
First Number: −5; Second Number: 5; 5 is larger than −5.

• Students recognize that if  < , then − > −,
because a number and its opposite are equal

Key Points
• Directed measurement --- a rational number’s position on the number line
is found using length and direction.
• The opposite of a number a, is –a. Both a and –a are located an equal
distance from zero, in opposite directions.
• Rational numbers represent real-world situations. We can write and
explain statements of order for rational numbers in real-world contexts.
• The absolute value of a number is its distance from zero; and can be used
in the context of a situation to show magnitude. We can use absolute
value and the symmetry of the coordinate plane to solve problems related
to distance.
