This traditional textbook style unit includes vocabulary, a direct explanation section, examples, practice problems that directly line up with the explanations and examples, and a unit summary review and practice problems. Learners get familiar with the vocabulary by doing a crossword puzzle, do a coordinate graphing lesson, practice finding the midpoint of a line given the end points, and write functions given different characteristics like the x-intercept and y-intercept. Finally, there is a review in two-column style for the lesson, a review, and practice test.
