Grade: Sixth
Essential Question
How can positive and negative numbers
help me to learn and understand realworld situations?
Big Idea
I can relate positive and negative numbers
to the real world by understanding that
they have a place on number lines in
relation to zero. Their place is based on
the sign of the number.
Journal Task
Explain a real world situation or event that
you have witnessed in your life by using
positive and negative numbers in your
writing.
Lesson 12 – Understand Positive and Negative Week: 9
Numbers
Standard 6.NS.C.5-6.NS.C.6 (a,
& c)
Understand that positive and
negative numbers are used
together to describe quantities
having opposite directions or
values.(e.g temperature above
or below zero etc.) use positive
and negative numbers to
represent quantities in realworld contexts, explaining zero
in each situation.
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
with negative number
coordinates.
A. Recognize opposite
signs as numbers on
opposite sides of 0 on
the number line,
recognize that the
opposite of the
opposite of a number
is the number itself, e.g
–(-3)=3 and that 0 is its
own opposite.
c. 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.
Vocabulary
, positive number, negative
number, rational number,
signed numbers, opposites,
integers, coordinated pairs,
coordinated plane, quadrants,
increasing, decreasing, vertical,
horizontal
Learning Targets
Relate positive and Negative numbers
to real world situations.
Understand integers and other rational
numbers as points on a number line.
Understand the sign of a number
indicates its direction on a number line
from zero.
Recognize that the opposite of an
opposite of a number is the number
itself; 0 is its own opposite.
