Chemistry: Ionic Compounds with the Transition Metals

Tutoring chemistry, ionic compounds with the transition metals often need extra attention because of the Roman Numerals. You can read my previous posts (Oct 20 and Oct 25) about writing ionic formulas.  Assuming you’re up to speed, we’ll discuss how …

Biology: How a Kidney Works

When you tutor biology or any science, often the basic concept is better without all the extra details thrown in. The renal artery brings blood to the kidneys to be filtered.  Upon reaching a kidney, the renal artery branches into thousands of arterioles, …

Tutoring high school chemistry, ionic compounds are fundamental.  We’ll discuss how to write their formulas when radicals and involved. In my Oct 20 post about the periodic table and ionic compounds, I mentioned the issue of metal vs nonmetal.  As I described …

Prime Factorization and Reducing Fractions

Continuing our discussion about the prime factorization, we focus on using it to reduce fractions containing large numbers.  In high school math, this application – happily – has resurfaced. You can read about prime factorization in my Oct 14 post.  Let’s …

Chemistry: the Periodic Table and Ionic Compounds

When you tutor high school chemistry, these basics come up every year.  Let’s sort them out. From the high school chemistry point of view, there are two types compounds:  ionic and covalent.  Ionic names start with a metal; covalent names contain only nonmetals. What …

Uses of Prime Factorization: Finding Least Common Multiple

We continue our exploration of prime factorization.  Any high school math tutor deals with the subject a few times a year. Continuing from our previous post, let’s investigate one use of the prime factorization:  finding the least common multiple (LCM) of two (or more) numbers. You can …

Prime Numbers and Prime Factorization

In math tutoring, prime numbers and prime factorization are receiving fresh attention.  We’ll briefly look at the concepts. Before we talk about prime numbers, let’s define factor.  In math, a factor is a number that divides into another number with …

Study Strategy

One question a math tutor – or any tutor – might be asked: “How do I prepare for an exam?”   We’ll examine a basic strategy. Exam preparation is an important process.  Few people like doing it, so a lot less of it …
