OVERCOMING MATH ANXIETY
Chapter 6. Everyday Math
The sequence in which elementary mathematics is taught may not be the only way to learn it. Instead of starting at the beginning, wherever that might be, we could start somewhere in the middle, with an interesting question that inevitably will bring us around, if not to the beginning, at least to other interesting mathematical ideas.
1. What is 25 percent of 24?
2. 6 is what percent of 24?
3. 6 is 25 percent of what?
It is estimated that 80 percent of all people questioned can solve the first problem; about 40 percent can solve the second; and perhaps only 10 percent can solve the third, especially if the numbers are not as simply related as the ones I have chosen here.
My conclusion from reviewing fractions as an adult is this: fractions
are difficult because they behave quite differently from whole
numbers and produce different results when used in familiar operations.
If fractions bewitch us, minus signs betray us. For, whereas the meaning of "minus" is rooted in subtraction,
"minus" has many usages that are not clearly explained to us the
first time around...
