Algebra Textbooks Evaluation

Idea Sets Used to Evaluate Algebra Textbooks

IDEA SET 1: FUNCTIONS

Representing Functions - NCTM Draft Standard 2.1#3, Grades 9-12
Select appropriate representations (numerical, graphical, verbal, and symbolic) for the functions and relations embedded in quantitative situations, convert flexibly among representations, interpret representations and use them to interpret the situations represented.

Modeling with Functions - NCTM Draft Standard 2.3#1, Grades 9-12
Model a wide range of phenomena with a variety of functions including linear, quadratic, exponential, rational, trigonometric, and recursively defined functions and recognize that a particular type of function can model many different situations.

IDEA SET 2: VARIABLES

Representing Variable Quantities - NCTM Draft Standard 2.2#1, Grades 9-12
Represent situations that involve variable quantities with expressions, equations, inequalities, and systems of equations using a variety of equivalent forms.

IDEA SET 3: OPERATIONS

Operating with Symbols and Equations - NCTM Draft Standard 2.2#3, Grades 6-8 and Draft Standard 2.2#2, Grades 9-12
Become fluent in generating equivalent expressions for simple algebraic expressions and in solving linear equations and inequalities. Develop fluency operating on polynomials, vectors, and matrices using by-hand operations for the simple cases and using technology for more complex cases.
