Description
Algebra 1 Notes and Assignments over Scatter Plots and Trend Lines.
TUTORIAL VIDEOS included (no prep to you!) and can be found on my YouTube Channel: mandy’s math world - the videos are on the Linear Functions Unit Playlist!
This product includes THREE days of lessons and assignments.
Day 1 introduces scatter plots, positive/negative/no correlations, and making predictions by interpolating and extrapolating data. Students will identify general correlations, draw trend lines and make predictions based on drawn trend lines.
Day 2 introduces linear regressions so that students may calculate exact lines of best fit. 2 VERSIONS are included:
- Version 1 includes directions on a TI-83/84 calculator
- Version 2 includes directions for the online Desmos application (found at www.desmos.com) - this is the application my students will use during remote learning if they do not have a graphing calculator. Students will use the linear regression to make predictions.
Day 3 incorporates correlation coefficients so that students may determine the strength of the data and validity of their predictions.
Please note: these lessons do not make students decide which type of function would best fit the data.
These are lessons 12-14 in my Linear Functions Unit Bundle!
