Course DescriptionThe goal of this course is to provide students with a foundation in the algebraic strand of mathematics through experiences with: understanding patterns, relations, and functions; representing and analyzing mathematical situations and structures using algebraic symbols; using mathematical models to represent and understand quantitative relationships; analyzing change in various contexts. Mathematics itself will be looked at not just as calculation but also as a modeling language, as a process for logical thought, and as a field of study. This approach to Algebra 1 is organized around families of functions, with special emphasis on linear functions. As students learn about each family of functions, they will learn to represent them in multiple ways: as verbal descriptions, equations, tables, and graphs. They will also learn to model real‐world situations using functions in order to solve problems arising from those situations.MAJOR UNITS OF STUDYMARKING PERIOD: 1Unit: Chapter 1 – Expressions, Equations, and FunctionsCommon Core StandardsInterpret parts of an expression, such as terms, factors, and coefficients.Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.Keystone Connections:A1.1.1.4 Use estimation strategies in problem solving situations.A1.1.2.1 Write, solve, and/or graph linear equations using various methods.A1.1.3.1 Write, solve, and/or graph linear inequalities using various methods.A1.2.1.1 Analyze and/or use patterns or relations.A1.2.1.2 Interpret and/or use linear functions and their equations, graphs, or tables.PA State Standards2.8.A1.D.

For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximationsApply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagramKeystone Connections:A1.1.1.1 Represent and/or use numbers in equivalent forms (e.g., integers, fractions, decimals, percents, square roots, and exponents).PA State StandardsStudent Objectives:Performing operations with real numbersApplying properties of real numbersClassifying and reasoning with real numbersMaterials &TextsAlgebra 1‐ Larson series –McDougal, Littell & Co.‐ 2007 ed.

Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers). Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations. For example, rearrange Ohm’s law V = IR to highlight resistance R.Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.Keystone Connections:A1.1.2.1 Write, solve, and/or graph linear equations using various methods.PA State StandardsStudent Objectives:Solving equations in one variableSolving proportion and percent problemsRewriting equations in two or more variablesMaterials &TextsAlgebra 1‐ Larson series –McDougal, Littell & Co.‐ 2007 ed.

For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function A = s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear).

Sketch a graph that exhibits the qualitative features of a function that has been described verbally.Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.Know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line.Keystone Connections:A1.2.2.2 Analyze and/or interpret data on a scatter plot.PA State Standards2.6.A1.C.
