Moreover, you might find that you needed that work later anyway. Don’t EraseĮrasing takes up valuable time. Does your last line of work answer the question? Did you address all parts of the question? Are your units correct? 8. Review the Problem StatementĪfter answering a question, go back and re-read the problem. You know you’ve over-used the calculator if your “work” consists of the phrase “The answer is _ because my calculator said so.” While it’s great for checking your work, don’t rely on those calculator features to solve the problem completely. Some approved calculators can do calculus procedures, including finding extreme values, intervals of increase/decrease, and concavity. Now this doesn’t mean you have to write, “I added 14.5 to 54.2 in the calculator to get 68.7.” Instead, the graders want to know when you have used the solver or numerical integration features, for example. However, you must indicate when and where you use a calculator function or program. You are encouraged to used built-in features of the calculator. In calculus, much of the work is in setting up and solving equations, working out derivatives or integrals, etc.īe sure to write down each expression or equation clearly before working with it. This might be where you work out sums and products, or verify your antiderivatives by taking a derivative, etc. Scratch includes mundane numerical computations, verification of your work, and other items that do not fit with the flow of your mathematical argument for the question.ĭesignate a small area of the page for scratch work. It’s important to separate scratch from mathematical steps. You will lead the reader from the given information to the final answer through a series of logical steps. It may sound strange, but the solution of a mathematical problem should read like a story. Do you have a strategy for solving the problem? What major steps go into the solution? 2. The most important tip is to make sure that you understand what the question is asking before writing anything down. (More info about those can be found here: Understanding AP Free Response Questions.) 10 Tips to Showing your Math Work You must show a logical progression of mathematical steps to receive credit on the free response questions. That’s an important part of learning mathematics.įurthermore, half of the AP Calculus exam requires you to show work. Instead, showing your math steps demonstrates that you know the process well enough to explain it to someone else.
