Q: How can it take at most 10 hours of your time to completely master a topic that is studied repeatedly every year starting with 3rd grade?

The reason is that Fractions are SIMPLE! But only if taught the right way, based on the principles I outline in the Teaching Philosophy section of the site.


Q: But I don’t need to know everything, I only want to know what the teacher teaches in class.

The answer is that it is easier to study all of it than some parts.


Q: How so? That doesn’t make sense.

The first reason is that in school, they teach you, for example, addition before they teach you multiplication. But to know addition of fractions you need to know multiplication of fractions first! And it is not your teacher’s fault; it is what teachers are told to teach.

The second reason is that you don’t get “cold”. The previous sections are fresh in your mind when you start a section and that makes it easier to learn. It is like playing after a warm up or starting to play without one.


Q: So I will learn it all in 10 hours but next year I will have to learn it again, right?

Not really. The way the book is designed is to ensure long-term memory. Firstly, because it is easy to understand and what we understand we remember. Secondly, it has enough practice to make sure you REALLY know it. Thirdly, each section uses things you studied in previous sections and therefore you practice them even more.

Of course, you might need to refresh your memory. But you will have the book (or you can redownload for free) to use. And you can use that book even in COLLEGE!


Q: Ok, I will master the skills, but will I REALLY understand the why?

Yes. Each concept or method you learn is accompanied by an explanation of the "why". I explain why it is like that, why it works, and the meaning of it. For example: most textbooks and schools don't teach the meaning of multiplying or dividing fractions because those are difficult ideas. In the book those are explained clearly. Further more, ALL possible meanings (and there are more than one)are explained by relating those to the meanings of whole number operations. Therefore,at the end of each section you master the skills and you understand the meaning and reasoning.
