Let's get to the root of those fractions

from By Denny Hydrick

How can anyone of us forget those dreadful fractions we were introduced to in junior high school? To this day, fractions still remain that same terrifying monster to many adults. How does inverting the second fraction and multiplying them make sense when dividing. That's like some modern diets where you are instructed to eat fat to lose fat ... something just doesn't seem right about that picture.

But, as with many of our learning techniques (then and now), some of us got more adept at manipulating fractions through practice. Perhaps that is why some adults still fear them because they don't practice enough?

I don't profess to understand everything about the so-called Common Core math taught in many schools today, but from what I can see of it, engineers and mathematicians have been practicing some of the same manipulations for years ... again from practice. Whether or not it should be taught in schools to kids who are still trying to understand "inverting" a fraction is not for me to say. more
