The main culprit behind the dropouts, the 3rd grade elementary school fraction!
If you don't understand and move on from fractions properly, you may end up a failure.

A 'completely precious fountain book' that breaks down concepts into small pieces so that you can't help but digest them completely!!!

1.
Visualize math terms to remember them for a long time!
Mathematics is a discipline of promise.
It is a study focused on concepts and processes, not simple calculations.
So, we need to know the terminology accurately, but the problem is that most mathematical terms are Chinese characters.
So, we have included the terms written in Chinese characters in the book in an easy-to-understand way and illustrated them so that you can remember them for a long time.
To avoid confusion, we explain it with pictures, and we practice it with problems so that you can internalize it completely.
You don't have to worry about fraction terminology anymore.

2.
Intuition comes first, logic comes second!
Before developing the logical content, we start with an intuitive understanding.
After learning how to distinguish between the shapes of fractions, we will begin to unravel the meaning of fractions.
First, see what half is, then practice 1/3, 1/4, … in that order, and then generalize to 1/□.
Because you first gain an intuitive understanding and then organize the concepts with logical explanations, you can naturally accept mathematical expressions and promises.


3.
You can practice changing sentences into equations!
Children who can solve problems easily when they are given a formula, but are at a loss when they are given a sentence.
But in fact, sentences and expressions are just different ways of expressing the same thing.
If you express a situation in words, it is a sentence, and if you express it mathematically, it is an equation.
English isn't the only language where sentences are broken up into pieces.
In mathematics, to change a sentence into an equation, you must read the sentence separately.
You can practice cutting sentences and replacing each part with what you want, and it provides a logical explanation of why you can make the changes.
You can practice changing sentences into formulas step by step, underlining sentences, and also marking them with parentheses.

Free video lectures so you can study on your own!
From the second chapter, which begins with a full-fledged mathematical story, video lectures are included.
You can view the lecture immediately without separate registration by scanning the QR code on the page.
You can enjoy studying with the cheerful, refreshing, and exhilarating lectures of a former EBS teacher.
