Students are introduced to calculus topics of limits, continuity, and derivatives, and gain a foundation of essential calculus skills.
Math
Unit 9
11th Grade
Unit 9, Limits and Continuity, is an introduction to the calculus topics of limits, continuity, and derivatives, and it provides a foundation in the essential calculus skill of thinking and reasoning about the infinitely small and the infinitely large while also arguing logically based on definitions and theorems. Students should leave this unit confident working with piecewise functions, finding finite and infinite limits of various types of functions graphically and algebraically, and rigorously defining continuity.
This unit also offers a useful opportunity to review and deepen knowledge of various types of functions, and rational functions in particular offer a useful opportunity to apply knowledge of limits, analyze asymptotes and removable discontinuities, and think about end behavior, while all function types help students to apply function transformations in different contexts. These skills are essential foundational knowledge for calculus, and this unit should be tailored to the specific strengths and weaknesses of students to maximize the utility of that flexibility.
If there is not time for a nine-lesson unit at this point in the year, Lessons 3 and 5 could be cut. If there is extra time, Lesson 5 could be expanded to practice more parent functions, and Lessons 7 and 8 could be expanded to practice working with rational functions, factoring, and manipulating functions algebraically. If the unit is shortened, consider cutting corresponding questions from the assessment as well.
Since this unit serves as an introduction to Calculus, the lessons are aligned to the Learning Objectives and Essential Knowledge described in the College Board's AP Calculus AB and AP Calculus BC Course and Exam Description in the place of Common Core State Standards.
Pacing: 11 instructional days (9 lessons, 1 flex day, 1 assessment day)
This assessment accompanies Unit 9 and should be given on the suggested assessment day or after completing the unit.
