
Write expressions that record operations with numbers and with letters standing for
numbers.
Identify parts of an expression using mathematical terms (sum, term, product, factor,
quotient, and coefficient).
Evaluate algebraic expressions given a specific value for their variables.
Perform arithmetic in the conventional order of operations.
Instructional videos in the hyperlinks above are meant to support C2.0 content,
but may use vocabulary or strategies not emphasized by MCPS.
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
Introducing
Algebraic
Expressions
Applications
and Modeling
Procedural
Skill
Students will
reason about realworld situations to
write, interpret,
and evaluate
algebraic
expressions.
Students will build
accuracy when
applying the rules for
order of operations
to simplifying
expressions.
Students will apply
the rules for order
of operations to
evaluate
expressions in a
real world context.

Multiplication or Division from left to right
Addition or Subtraction from left to right
Note: Students are not taught to simply rely on pneumonic
devices such as PEMDAS or Please Excuse My Dear Aunt
Sally because they can lead to the misconception that
Addition always be performed before Subtraction and
Multiplication should always be performed before Division.

x and y are variables in the expression
Use a take-out menu or a sales advertisement to write an expression to
describe an order or purchase and then simplify it.
o Sample Menu: Sandwich Stop
o 2 Garden Sandwiches and 1 cookie written as 2g  1c
o Substitute in the prices. 2  6.95  2.00
o Simplify.
2  6.95  2.00


Play Make 24
o Use four numbers and addition, subtraction, multiplication,
division, and parentheses to make 24.
o For added challenge, include exponents as an option.
