This activity was created for middle school math stations on linear models. As students rotate through stations, they can be challenged in individual, partner, and group activities and games. This is an individual practice station. Here, students work independently on a guided problem solving activity. It requires students to make a scatterplot, then informally fit and assess a linear model. I laminate the included student directions to keep at the station.

Look out for this activity and many others in my eight grade bundles at a deep discount!!! Coming Soon!

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.
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.
Use the equation of a linear model to solve problems in the context of bivariate measurement data, interpreting the slope and intercept. For example, in a linear model for a biology experiment, interpret a slope of 1.5 cm/hr as meaning that an additional hour of sunlight each day is associated with an additional 1.5 cm in mature plant height.
