Lost points on a problem? What to do…

People don’t like losing points for errors in their solution of a problem.  So, what can you do to insure you won’t lose points again the next time you are given a similar problem?  Most folks seem to look through the corrections, then perhaps ask the teacher to solve the problem for the entire class, and perhaps even make a note to study that type of problem before the next test or quiz.  Few do more than that… and the next time they are given a similar problem the probability they will lose points unfortunately remains greater than zero.

The solution I advocate to this dilemma involves a combination of repetition and self-awareness.

Every problem you lose points on, whether on homework, a quiz, or a test, should be copied neatly onto a new Continue reading Lost points on a problem? What to do…

Getting the most out of standardized test (SAT, ACT) practice books

1) For the SAT, I prefer the study guide and practice tests published by The College Board (it can be found at Amazon: The Official SAT Study Guide (2016 Edition)) as it contains good scoring guides and is published by the authors of the test. The College Board is now also providing on-line practice test resources, as well as an app for your phone which provides daily practice problems.

2) Most formulas needed to answer SAT questions will be given at the start of the test section.  Overall, it is more important to know how to use a formula than it is to memorize it.  In studying for the SAT, focus on understanding the mathematics instead of memorizing facts or formulas.

3) Always time yourself when taking a practice test.  This will help you develop a Continue reading Getting the most out of standardized test (SAT, ACT) practice books

Operations are taught in pairs

Many High School students I have worked with have not spent much time pondering the sequence in which math topics were taught to them. So, it can be interesting to step into the “waaay-back” machine and investigate this question a bit:

What was the very first arithmetic operation you were taught (probably in first grade)? What operation were you taught next? Why did your teacher choose this sequence?

If you followed the usual path, the first operation you learned was addition, and the second subtraction. Addition is the operation that describes things being joined or collected together: if I have three cookies, then two more are given to me, I add the two numbers to determine how many cookies I have. Addition is probably the most frequently Continue reading Operations are taught in pairs

Improve Your Math Grade: Use Scrap Paper

Never solve math homework problems on the piece of paper you intend to hand in (unless it is a problem that is very, very easy for you).

I used to do my work on the same piece of paper I intended to hand in, and when I encountered a problem I was uncertain about… I froze. I did not dare write anything incorrect on the page I was going to hand in. If I did, I might have to recopy all my work in order to end up with a neat-looking page to hand in. So, I would just skip the problem, telling myself I would ask the teacher about it in class next time. The result was that I greatly slowed my learning how to do that type of problem.

I now know that if I figure out how to do a problem all by myself, I will remember how to solve it for years. But, if I ask someone else how to do a problem I was struggling with, I will probably Continue reading Improve Your Math Grade: Use Scrap Paper
