Recent Tutoring Session Reviews
"We reviewed disk and washer methods for calculating volume. The student is comfortable with these problems, which is good because she has a test covering that material. We also did some review on limits and derivatives. The student needs to review the material from the beginning of the year. After her exam, the student plans to begin reviewing."
"The student recently got back her first test so we went over several problems from it as well as from the quiz. We reviewed both linear and quadratic equations including vertical and horizontal lines, how to put them into the various forms, and how to find key points on their graphs. We also reviewed compound interest both continuous and discrete as well as how to calculate the interest rate."
"We looked at sigma notation and specifically how to write arithmetic and geometric series in sigma notation. I noticed most of what seemed difficult was all the new terms and what they were used for and what they did. Of course, going back and forth between the arithmetic and geometric series S sub n formula was a little confusing, as were the use of exponents, but towards the end of the homework, the student was getting the hang of it. It's important in these problems to identify the first term in the series and the common difference d (for arithmetic) and the common ratio r (for geometric). It's also good to double-check your arithmetic or geometric formula for the first couple of terms (a1, a2, a3) to see if they match the terms you were given. We also had to use natural logarithms to find out the nth term of a geometric series when solving for n. We worked through the homework and learned some valuable problem-solving skills."
"We covered trinomial equations today. Using different methods such as the quadratic formula, completing squares, square roots, and factoring, we solved practice test questions he was given at school. I also made sure I gave him some practice questions to work on."
"The student doesn't have any more math this year, so we worked on practicing the basics. We worked on percents, decimals, and fractions, as he has had the most trouble with them in the past. We worked on multiplication and addition with percents, decimals, and fractions. After we did some practice, I gave the student two quizzes. He only missed one on the first, and that was simply because he didn't reduce completely. He got 100% on the second. After that, he played some math learning games on the computer. We will quiz him some more next week, but I feel that he has the basics firmly under his belt, and he is quite ready for the next grade."
"The student and I went over her geometric series section of the book and the problem sets she was assigned. We also went over the formulas she'll have to have memorized for tomorrow's quiz. Her final will be next Thursday."
