Overview and List of Topics

PLEASE SPREAD THE LOVE :)

MathHints.com (formerly SheLovesMath.com) is a free website that includes hundreds of pages of math, explained in simple terms, with thousands of examples of worked-out problems. Topics cover basic counting through Differential and Integral Calculus! Use Math Hints to homeschool math, or as a supplement to math courses at school. Math Hints was developed by Lisa Johnson, who has tutored math for over \(25\) years.

My philosophy on teaching math:

  • You can’t study for math tests without doing problems! A lot of times, I think I know the subject I’m tutoring (by looking at the book), and then when I get in there and start solving problems, I realize that I didn’t know it as well as I thought I did!
  • Learning math should be an active experience and should relate to the world. And always use “simpler numbers” if a problem’s numbers are complicated. For example, paying \(\$4\) for \(2\) oranges makes it more obvious that you need to divide than paying \(\$5.88\) for \(3\) oranges.
  • Learning math requires an understanding of what to “memorize” (for example, the tools), and what to “understand”.  We don’t need to reinvent the wheel; it’s already been invented. Don’t worry if you have to memorize something with math without “understanding” it!
  • Learning more advanced math is no more than building on what is already known: if you can add \(2+2\), and build with math tools, you can be taught to solve a complicated Calculus problem.
  • Math books tend to “brag” and try to explain things with difficult words that sometimes don’t make sense! Math can be explained more easily with every day words.
  • Sometimes there’s just one little concept that isn’t known or understood that makes a whole new math concept difficult. We need to find that and learn it!
  • Math = Rules + Examples + Practice, Practice, Practice!!!
