Use variables to represent numbers and write expressions, equations, and inequalities when
solving a real-world or mathematical problem.
Use substitution to determine whether a given number makes an equation or inequality true.
Represent the solutions of inequalities on number lines.

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
Deep
Conceptual
Understanding
Equations and Inequalities
Applications
and Modeling
Procedural
Skill
Students will
understand that
the solution of an
equation or
inequality is the
value of the
variable that makes
the equation or
inequality true.
Students will build
accuracy when
solving equations and
inequalities.
Students will apply
the idea of
maintaining the
equality of both sides
of an equation or
inequality to solve
simple one-step
equations and
inequalities.

Solve for unknowns in real-world situations and practice representing the
situations as equations:
o I bought some apples at the farmer’s market last week and then I
bought 4 more at the store. Now I have 16 apples. If I still
haven’t eaten any of my apples, how many did I buy last week?

The inequalities above are presented with no context, therefore all solutions must be
considered. In problems with context, students need to reason about the solution. For
example, if the first inequality represented greater than 2 people, only the whole numbers
should be represented on the number line because you can’t have 2.5 people.
I have saved 3 times as much money as Pete. Pete saved $13.56.
