Understand that an algebraic expression is
simply a way to show a number if we don’t
know all its parts
Be able to translate words into algebraic
expressions
Understand that each term in an algebraic
expression (2xy) has a “what” (in this case
xy) and a “how many” (in this case 2)
Understand the difference between adding
or subtracting terms and multiplying terms
(x + x is different than x * x)
Be able to add or subtract terms and
multiply or divide terms
Understand the difference between adding
terms and combining terms (One can add
any two terms together, but one can only
COMBINE like terms)
Understand the Distributive Property and
how to distribute both multiplication and
division.
Be able to fully simplify algebraic
expressions by the steps discussed in class
(turn subtraction into addition, distribute
multiplication and division, then combine all
like terms)
Understand the similarities between how
algebraic terms and fractions are similar
when it comes to the four operations
(possible essay)
Be able to find expressions to stand for the
area and perimeter of various shapes

Polynomials:

Pg 122: 28-38 evens
Understand the following vocabulary terms:
o Monomial
o Binomial
o Trinomial
o Polynomial
Be able to determine the degree of an
expression by examining the exponents of
the variables in the term (the largest
exponent in a term sets the degree for the
expression)
