# Course Syllabus for Beginning Algebra

Algebra Standard

Understand patterns, relations, and functions
▪ generalize patterns using explicitly defined and recursively defined functions;
▪ understand relations and functions and select, convert flexibly among, and use various representations for them;
▪ analyze functions of one variable by investigating rates of change, intercepts, zeros, asymptotes, and local and global behavior;
▪ understand and perform transformations such as arithmetically combining, composing, and inverting commonly used functions, using technology to perform such operations on more-complicated symbolic expressions;
▪ understand and compare the properties of classes of functions, including exponential, polynomial, rational, logarithmic, and periodic functions;
▪ interpret representations of functions of two variables.

Represent and analyze mathematical situations and structures using algebraic symbols
▪ understand the meaning of equivalent forms of expressions, equations, inequalities, and relations;
▪ write equivalent forms of equations, inequalities, and systems of equations and solve them with fluency—mentally or with paper and pencil in simple cases and using technology in all cases;
▪ use symbolic algebra to represent and explain mathematical relationships;
▪ use a variety of symbolic representations, including recursive and parametric equations, for functions and relations;
▪ judge the meaning, utility, and reasonableness of the results of symbol manipulations, including those carried out by technology.

Use mathematical models to represent and understand quantitative relationships
▪ identify essential quantitative relationships in a situation and determine the class or classes of functions that might model the relationships;
▪ use symbolic expressions, including iterative and recursive forms, to represent relationships arising from various contexts;
▪ draw reasonable conclusions about a situation being modeled.

Analyze change in various contexts
▪ approximate and interpret rates of change from graphical and numerical data.

Geometry Standard

Analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationships
▪ analyze properties and determine attributes of two- and three-dimensional objects;
▪ explore relationships (including congruence and similarity) among classes of two- and three-dimensional geometric objects, make and test conjectures about them, and solve problems involving them;
▪ establish the validity of geometric conjectures using deduction, prove theorems, and critique arguments made by others; • use trigonometric relationships to determine lengths and angle measures.

Specify locations and describe spatial relationships using coordinate geometry and other representational systems
▪ use Cartesian coordinates and other coordinate systems, such as navigational, polar, or spherical systems, to analyze geometric situations;
▪ investigate conjectures and solve problems involving two- and three-dimensional objects represented with Cartesian coordinates.

Apply transformations and use symmetry to analyze mathematical situations
▪ understand and represent translations, reflections, rotations, and dilations of objects in the plane by using sketches, coordinates, vectors, function notation, and matrices;
▪ use various representations to help understand the effects of simple transformations and their compositions.

Use visualization, spatial reasoning, and geometric modeling to solve problems
▪ draw and construct representations of two- and three-dimensional geometric objects using a variety of tools;
▪ visualize three-dimensional objects and spaces from different perspectives and analyze their cross sections;
▪ use vertex-edge graphs to model and solve problems;
▪ use geometric models to gain insights into, and answer questions in, other areas of mathematics;
▪ use geometric ideas to solve problems in, and gain insights into, other disciplines and other areas of interest such as art and architecture.

Measurement Standard

Understand measurable attributes of objects and the units, systems, and processes of measurement
▪ make decisions about units and scales that are appropriate for problem situations involving measurement.

Apply appropriate techniques, tools, and formulas to determine measurements.
▪ analyze precision, accuracy, and approximate error in measurement situations;
▪ understand and use formulas for the area, surface area, and volume of geometric figures, including cones, spheres, and cylinders;
▪ apply informal concepts of successive approximation, upper and lower bounds, and limit in measurement situations;
▪ use unit analysis to check measurement computations.
Data Analysis and Probability Standard

Formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them
▪ understand the differences among various kinds of studies and which types of inferences can legitimately be drawn from each;
▪ know the characteristics of well-designed studies, including the role of randomization in surveys and experiments;
▪ understand the meaning of measurement data and categorical data, of univariate and bivariate data, and of the term variable;
▪ understand histograms, parallel box plots, and scatterplots and use them to display data;
▪ compute basic statistics and understand the distinction between a statistic and a parameter.

Select and use appropriate statistical methods to analyze data
▪ for univariate measurement data, be able to display the distribution, describe its shape, and select and calculate summary statistics;
▪ for bivariate measurement data, be able to display a scatterplot, describe its shape, and determine regression coefficients, regression equations, and correlation coefficients using technological tools;
▪ display and discuss bivariate data where at least one variable is categorical;
▪ recognize how linear transformations of univariate data affect shape, center, and spread;
▪ identify trends in bivariate data and find functions that model the data or transform the data so that they can be modeled.

Develop and evaluate inferences and predictions that are based on data
▪ use simulations to explore the variability of sample statistics from a known population and to construct sampling distributions;
▪ understand how sample statistics reflect the values of population parameters and use sampling distributions as the basis for informal inference;
▪ evaluate published reports that are based on data by examining the design of the study, the appropriateness of the data analysis, and the validity of conclusions;
