Interpret expressions that represent a quantity in terms of its context.

a. Interpret parts of an expression, such as terms, factors, and coefficients.

b. Interpret complicated expressions by viewing one or more of their parts as a single entity.

Use the structure of an expression to identify ways to rewrite it.

Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.

a. Factor a quadratic expression

b. Complete the square in a quadratic expression to reveal the maximum or minimum value

of the function it defines.

Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.

Combine standard function types using arithmetic operations.

UNIT DESCRIPTION

Students will become fluent in simplifying and identifying the parts of expressions. This includes using the order of operations, simplifying polynomial expressions, and simplifying expressions with exponents.

-Identify: terms, factors, coefficients, bases, and exponents

-Operations with polynomials (add, subtract, and multiply).

Students will become fluent in factoring quadratic expressions.

-Include GCF’s, difference of squares, trinomials method for all values of A and grouping.

Students will be able to translate a verbal expression to an algebraic expression.

Activity: Intelli-Gum – These interesting activity sheets were created to introduce polynomial operations. To do this Don

“invented” a product call “Intelli-Gum” which comes in several different sizes containers.

Students use polynomial operations to make, process, and consolidate orders.

Activity: Animal Populations - In this task, students have to interpret expressions involving 2 variables in the context of a real world situation. All given expressions can be interpreted as quantities that one might study when looking at 2 animal populations

.

Activity: Delivery Trucks The task has students look for structure in algebraic expressions related to a context, and asks them to relate that structure to the context. In particular, it is worth emphasizing that the task requires no algebraic manipulation from the students.

Activity: Kitchen Floor Tiles - The purpose of this task is to give students practice in reading, analyzing and constructing algebraic expressions, attending to the relationship between the form of an expression and the context from which it arises.
