Math can be hard. Students will complain about it. People long out of school will sometimes seem to have a shiver run up their spines thinking back to their last brush with it. So, how does a person teach it well?
Above all, math is cumulative. If you cannot remember the basics, it is very hard to move on to the complex. And according to About.com, if students eked out a C in their last class, they are really moving on to the next class having only “absorbed and understood about half of what they should.”
