This product contains 8 Linear Labs with grading rubric and 3 comprehensive test questions with solutions. Each group of 2 to 4 students work on separate labs, taking measurements, and recording data and graphing on the data tables and grids provided. Groups draw a line of best fit, determine the equation for the line, and give the real world meaning of the slope and intercepts using the units in the problem. Lab groups prepare a poster and give a presentation. Word and Excel scoring rubrics are included. 3 test problems are included with solutions. I use this in both Algebra 1 and 2, requiring Algebra 2 students to determine the Median-Median line.
The Common Core State Standards:
S-ID.6. Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.
a. Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear, quadratic, and exponential models.
S-ID.7. Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.
