Quadratic Word Problems Common Core Algebra 1 Homework
Joe Brennon
This product includes a lesson plan and video lecture with worksheet and answer key aligned with the common core. Students review how represent the relationship between two quantitative variables on a scatterplot. Students learn how to fit and interpret linear regression models; how to compute and interpret the correlation coefficient of a linear fit; how to interpret, plot, and analyze residuals; and how to distinguish between correlation and causation. The worksheet can be used as an in-class handout or as homework. Questions assess statistical reasoning as well as mechanics. The video can be used for flipped classrooms, a sub activity, or a way to stay on schedule during excessive school closings.
This lesson reviews linear functions, linear models, and correlation and further emphasizes evaluating the fit of a linear model. A complete video lesson on functions (linear, quadratic, and exponential) that describe the relationship between two quantitative variables can be found here.
A similar analysis of the quadratic functions test bank really hit home the variety of techniques students needed to apply to find and solve quadratic equations. I also noticed that a majority of the word problems dealt with some form of accelerated motion so I made a mental note that a project problem involving accelerated motion would nicely align to the quadratic functions standards.
