Lake County Schools Investing In Excellence! College and Career Readiness Academic Services April 2013 AP Seminar For Advanced Placement Calculus AB _______ WELCOME Community Builder: Just like me….. 1. 2. 3. 4. One person begins introducing themselves to the group When another person in the audience hears something the previous person shared that is “just like them” they chime in and say “ that’s just like me” The person that chimed in saying “ that’s just like me” begins introducing themselves starting with the connection from the previous person. Repeat step 2 and 3 until all members in the audience have introduced themselves. Bellwork: Community Builder •Instructor will review the 21st Century skills and AP success stats with students and make a connection to the AP Seminar •Instructor will review specific content for AP course of study Learning Goal: Learners will understand and implement effective test taking strategies for passing AP exams. I DO Benchmarks: Strategic Plan Goal # 1 Increased Student Achievement Objective April 6 & April 27 2013 AP Seminar CBC •Learners will: utilize content knowledge learned in AP courses coupled with effective test taking strategies to increase pass rate by completing practice AP test questions WE DO •Students will utilize materials YOU DO from the AP Seminar to study for AP exam Essential Question: How do we revolutionize the way we teach, lead, and learn for 21st century success?

How the test is graded: • Multiple Choice: 50% of your grade – 1.2 points for each correct – 0 points for incorrect/blank • Free Response: 50% of your grade – Each question is graded on a scale of 0-9 – No “bald” answers are given credit – show work Parts of Test: Multiple Choice: Part A 28 problems in 55 min (NO calculator) Part B 17 problems in 50 min (calculator allowed) Free Response: Part A Part B 2 problems in 30 mins (calculator allowed) 4 problems in 1 hour (NO calculator) * *You may go back and work on first two problems but you may NOT use calculator. Multiple Choice Strategies • • • • • • • Do easy problems first! Do not linger-let the hard ones go. Read the question carefully. Graph or chart- is it f (x) or f '(x)? Do not round until the final answer Perhaps you can work backwards If all else fails – guess!

Find Absolute Extrema on [a,b] (also known as global) Check endpoints and critical numbers to find extreme y values. Relative Extrema (also called local) May occur where f’=0 or f’ undefined Find inflection points: Find f’’(x) to see where concavity changes signs.
