IB Math SL Summer Assignment 2019-2020 The IB Math SL curriculum covers six different mathematical topics (algebra, functions, trigonometry, vectors, statistics, and calculus). Three of these six topics were thoroughly covered in your Pre-Calculus class (algebra, functions, and trigonometry). In an effort to best prepare you for the IB paper exams at the end of the year, three topics need to be reviewed during the summer. This will leave the class with more time during the school year to focus on statistics and calculus. The summer assignment will be broken up into three sections in which I have written a suggested timeline in which they should be completed: Topic 1: Algebra- finish by June 22nd Topic 2: Functions- finish by July 13th Topic 3: Trigonometry- finish by July 31st Every topic should be turned in by the first day of class. Please complete all work in sequential order on separate paper and write your final answers on the actual assignment. The summer assignment will be worth a quiz grade and there will be a test over this material within the first three weeks of the school year. To assist you in each topic, here are links to video tutorials: https://sites.google.com/a/roundrockisd.org/kyle-bell/ib-math-sl-summer-assignment https://osc-ib.com/ib-revision-videos I also suggest using notes from your previous Pre-Calculus course along with the attached formula booklet for reference. This formula booklet is what you will be allowed to use on the paper exam. If you have any questions, you can email me at [email protected] and I will return your email as soon as I can. Have a wonderful summer! I look forward to seeing you next year! Mr. Anand Name: Topic 1: Algebra Topic 2: Functions *The circle indicates the origin.
