Description:

This module was written for a Pre-Algebra or Algebra I class in mind. It will lead students through the process of graphing data and finding a line of best fit while simultaneously exploring the characteristics of linear equations in algebraic and graphic formats. These topics are then tied back into real-world experiences in which people use linear functions. During the module, students utilize these scientific concepts to solve the following problem: You are a new researcher in a lab, and your boss has just given you your first task to analyze a set of data. It being your first assignment, you ask an undergraduate student working in your lab to help you figure it out. She responds that you must determine what the data represents and then find an equation which models the data. You determine that you will be able to determine what the data represents on your own, but you ask for further help modeling the data. In response, she says she is not completely sure how to do it, but gives a list of equations that may fit the data. This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn.

CCSS.Math.Content.8.EE.B.5: Common Core State Standards for Mathematics

Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.

CCSS.Math.Content.8.EE.B.6: Common Core State Standards for Mathematics

Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.

CCSS.Math.Content.8.EE.C.8a: Common Core State Standards for Mathematics

Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.

CCSS.Math.Content.8.EE.C.8b: Common Core State Standards for Mathematics

Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection.

CCSS.Math.Content.8.EE.C.8c: Common Core State Standards for Mathematics

Solve real-world and mathematical problems leading to two linear equations in two variables.

CCSS.Math.Content.HSA-CED.A.2: Common Core State Standards for Mathematics

Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.

CCSS.Math.Content.HSA-CED.A.3: Common Core State Standards for Mathematics

Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or nonviable options in a modeling context.

CCSS.Math.Content.HSA-CED.A.4: Common Core State Standards for Mathematics

Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations.

CCSS.Math.Content.HSF-IF.B.4: Common Core State Standards for Mathematics

For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship.?

CCSS.Math.Content.HSF-IF.B.5: Common Core State Standards for Mathematics

Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes.?

CCSS.Math.Content.HSF-IF.B.6: Common Core State Standards for Mathematics

Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph.?

CCSS.Math.Content.HSF-IF.C.7a: Common Core State Standards for Mathematics

Graph linear and quadratic functions and show intercepts, maxima, and minima.

CCSS.Math.Content.HSF-IF.C.9: Common Core State Standards for Mathematics

Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).

CCSS.Math.Content.HSF-BF.B.3: Common Core State Standards for Mathematics

Identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them.

CCSS.Math.Content.HSF-LE.A.2: Common Core State Standards for Mathematics

Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).

CCSS.Math.Content.HSG-GPE.B.5: Common Core State Standards for Mathematics

Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point).
