```Vocabulary Associated with Algebraic Expressions
CONTEXT OF LESSON/PRE-REQUISITE KNOWLEDGE:

Students have been introduced to translating verbal expressions to algebraic expressions.
They have learned terms/phrases for addition, subtraction, multiplication, division, and
exponents.
 Students should know what an operation is and know the difference between an
expression and equation.
 Students should be able read and comprehend basic math vocabulary, take notes, and
listen attentively during direct instruction (20-30 minutes). Additionally, students should
be able to work in small learning groups and remain on task with minimal redirection for
up to 20 minutes.
LEARNING OBJECTIVES:




Students will learn vocabulary associated with algebraic expression, including: variable,
term, constant, and coefficient.
Student will be able to identify a variable, term, constant, coefficient, and an algebraic
expression or equation.
Students will be able to translate verbal phrases into algebraic expressions and algebraic
expressions into verbal phrases.
Students will be able to write, read, and evaluate algebraic expressions in which letters
stand for numbers.
CCGPS STANDARDS OF LEARNING:
Interpret expressions that represent a quantity in terms of its context. (Emphasis on linear
expressions and exponential expressions with integer exponents.) (DOK 2)

MCC9-12.A.SSE.1

MCC9-12.A.SSE.1a Interpret parts of
an expression, such as terms, factors, and coefficients.(Emphasis on linear
expressions and exponential expressions with integer exponents.) (DOK 2)
Vocabulary
o Algebraic Expression—contains at least one variable, one number and one
operation. An example of an algebraic expression is n + 7.
o Variable—a letter that is used in place of a number. Sometimes, the variable will
be given a value. This value will replace the variable in order to solve the equation.
Other times, the variable is not assigned a value and the student is to solve the
equation to determine the value of the variable.
o Constant—a number that stands by itself. The 7 in our previous vocabulary term
is an example of a constant.
o Coefficient—a number in front of and attached to a variable. For example, in the
expression 8x + 3, the 8 is the coefficient.
o Term—each part of an expression that is separated by an operation. For instance,
in our earlier example n + 7, the terms are n and 7.
Pre - Assessment: “Naming Parts of Expressions”
o Distribute to students “Naming Parts of Expressions” worksheet. This assignment should
be used to formatively assess students and to place in appropriate groups for the activity.
Differentiated Activities

Support – Part 1: Students should be divided into teams (2 to 3 to a team). Players
should take turns answering problems and checking their partners answer until all
problems are answered. After students have mastered these problems, their team can
move to Support – Part 2 or one of the On Target tasks.

Support – Part 2: Cut cards out on two different colors of paper (verbal expressions on
one and algebraic expressions on another). Students should match the cards accordingly
and explain their reasoning to their partner. After students have mastered this task, their
team can move on to one of the “On Target” tasks.

On Target – Part 1: Students should be divided into collaborative pairs. One student
receives worksheet “Verbal and Algebraic Expressions – Sheet A” and the other student
receives worksheet “Verbal and Algebraic Expressions – Sheet B”. Students work
individually and then compare their answers after both are finished. Students should
discuss their answers with their partner. (or you can use Sheet C and D together or Sheet
E and F together) After students have mastered this task, their team can move to Support

Extend – Part 1: Students can work alone or in collaborative pairs. Students should
match the verbal expression with the algebraic expression. If students are working in
pairs, they should discuss their answers with their partner. When students have mastered
these problems, they can move on to Extend – Part 2 activity.

Extend – Part 2: Teacher needs to cut out puzzle pieces before distributed to the
student. Students can work alone or in collaborative pairs. Students should match the
puzzle pieces accordingly. If students are working in pairs, they should discuss their
answers with their partner. The teacher should check for accuracy.
