January Topic: Linear Functions & Statistics Grade: Algebra 1 Big Idea: Students will learn how to solve a system of equations graphically and approximately from real-world and mathematical problems. Students will also learn how to identify the solution set of a system of inequalities graphically and algebraically. Students will apply their knowledge of linear functions to investigate patterns of association in bivariate data. Essential Information: I- Review of Comparing Linear Functions Comparing rates of change, initial value, domain, range, etc. in terms of the context the function models on specific intervals. II – Graphing Linear Systems Understand that the intersection of two equations in two variables is the solution. Create a system of equations from a word problem and solve graphically. Estimate the solution of a system of equations graphically. Understand that if a system of equations has no solution the lines are parallel. Understand that if a system of equations has infinite solutions the lines are coincident. II – Systems of Inequalities Understand that the solution set of a system of linear inequalities is the intersection of their corresponding half planes. Create and solve a linear system of inequalities graphically from a word problem Create and solve a linear system of inequalities algebraically from a word problem III – Statistics Know the different types of data and how to distinguish between them o Univariate vs. bivariate o Qualitative vs. quantitative Construct and interpret scatter plots to display data o Positive, negative, or no correlation o Outliers? o Linear or nonlinear relationship Drawing a line of best fit in a scatter plot to show the relationship between the data and determining its linear equation (using the graph and/or by using technology). Interpolate and extrapolate information from the scatter plot and line of best fit about the data. Understand if the data forms a causal relationship based on the scatter plot or by the data displayed in a chart IV – Volume Know the formulas for volume of a cylinder, sphere, and cone. Apply the formulas for volume to solve real-world and mathematical problems. o Including problems that require the formula to be rearranged when solving for a missing value, such as the height.

Understanding how to construct and interpret scatter plots for bivariate data to investigate patterns of association between two quantities. Understanding how to draw a line of best fit to model relationships between two quantitative variables and to informally assess the model fit by judging the closeness of the data points in the line. Understanding how to interpolate and extrapolate information from the equation of a line of best fit to solve problems. Understanding how to determine whether or not bivariate data has a causal relationship, and constructing and interpreting tables summarizing data collected from subjects.
