This is the shell lesson I created to go along with my Pre-Calculus textbook. It includes graphing of coordinates, derivation and application of distance formula, and derivation and application of midpoint formula. The lesson ends with a plexer of the day puzzle. Could also be used for a College Algebra or Algebra 2 course, or to supplement homeschooling. I base it off of the Larson Pre-Calculus book, Pre-Calculus with Limits.
