The Baltimore County Public Schools Algebra 1 program is designed so that each student has access to rigorous instruction, uses problem solving to examine the world around them, and engages in the habits of mind of proficient mathematical thinkers.
In Algebra 1 instructional time focuses on (1) expanding understanding of linear equations, inequalities, and systems of linear equations and inequalities, applying to scatter plots and lines of best fit, (2) deepening understanding of functions including notation, average rate of change, domain and range, specifically for linear, quadratic, exponential, and piecewise functions; (3) writing, transforming, graphing, and solving quadratic equations by reasoning, rearranging equations into useful forms and applying the quadratic formula; and (4) expanding statistical tools to interpret data including standard deviation, interquartile range, categorical data, and scatter plots.
