Recent Tutoring Session Reviews
"The student worked on using data to build frequency tables, cumulative frequency table, and histograms. He also reviewed linear and quadratic equations. He's showing improvement. He was able to answer the quadratic and linear equation questions with little or no help. He was able to answer the frequency and cumulative frequency questions on his own at the end of the session also. I left him with five linear and quadratic equations to graph for practice."
"The student's chemistry study guide homework was pretty hard, demanding definitions and a deeper understanding of several concepts including ionic bonds, covalent bonds, polar (covalent) bonds, and polar molecules. I think the studying effort on both our parts will be worthwhile."
"The student's class has been investigating exponential growth by examining number patterns and graphs. Today, I showed him how to calculate annual totals in an account with a given initial investment and interest rate. We also discussed how one can find the growth rate given the initial investment ($400) and a total accumulated amount a given number of years later ($56000 after 9 years) using the formula y = P*r^x. For one example, he was given the total amount after 9 years and the initial investment. We solved for x in the equation 56000*f^x. We also discussed biological life (bacteria) with an initial amount and the amount present after November."
"The student's homework tonight was exponential functions. He didn't have too much trouble with what we were doing. I got the sense that some of what we were looking at wasn't completely intuitive for him yet, which is the main goal of what I'm doing. We will continue to work on this."
"The student's homework was on solving polynomials by factoring. Only the word problems gave him a little difficulty, but not much. The last word problem led us into a long talk about how orbits work. I am so happy that he is so interested in these science concepts. It can really help put the more tedious math work into perspective."
"The student's new unit covers functions and their inverses. I went over my take on what functions are, what they mean, and a different way to look at them both algebraically and graphically to make it easier to deal with them. I made sure that he understood that a function's inverse is simply the original reflected across the line y = x. We had a very good session and zipped through his assigned homework quite readily. He has a good grasp of these concepts."
