The Common Core State Standards require a balance of three fundamental
components that result in rigorous mathematics acquisition: deep conceptual
understanding, procedural skill, and mathematical applications and modeling.
RIGOR
Extending the Number Line
Deep
Conceptual
Understanding
Applications
and Modeling
Procedural
Skill
Students will extend
their understandings
of number and
ordering of numbers
to the rational
number system,
which includes
negative rational
numbers.
Students will build
accuracy when
describing the value or
position on a number
line of positive and
negative numbers.
Students will model
real-world contexts
involving positive
and negative
numbers on vertical
and horizontal
number lines.

Sea Level from nrich.maths.org provides a good graphic as well
as guiding questions.
Position a number, its opposite, and the opposite of its
opposite on a number line.
o
The opposite of 8 is −8. The opposite of −8 is 8.
The opposite of the opposite of 8 is 8.
