Start with fractions of equal size.

In textbooks, fractions of equal size are written in a single line! "You can create fractions of equal size by multiplying or dividing the numerator and denominator by the same non-zero number." This is a crucial fact, but the reason for this is not explained in detail.
They just tell you to memorize it and then try to solve a lot of problems.

However, the Elementary Fraction Concepts Book 3 visually shows why this is so and explains the principles in a friendly way.
To avoid boredom, we present pictures of various shapes and explain at children's eye level using grouping and splitting.
Through this process, you will naturally learn that there are many different fractions of the same size.


2.
We also don't miss out on [divisors and multiples], which are inseparable from common denominators and fractions.

After learning about fractions of equal size, we move on to common denominators and reductions.
But before that, you absolutely must learn factors and multiples! Factors and multiples only involve natural numbers, so they might seem unrelated to fractions, but they're crucial to mastering fractions.
Factors, multiples, common divisors, common multiples, greatest common divisor, least common multiple - unfamiliar terms that appear all at once in fifth grade.
This book provides a quick overview of what each term means, why it's named that way, and how to remember it.

The most important [reduction and common denominator] in 5th grade fractions

Reduction and common denominator are the domain of operations.
So it's a good idea to provide different calculation methods for each type.
It reduces errors and speeds up calculations.
However, it is meaningless to just memorize the types and corresponding methods.
There is a reason why convenient calculation methods were created.
This book explains the reasons and principles in detail.
So that you can learn it naturally without having to mechanically solve countless problems.

Free video lectures so you can study on your own!

The book itself is packed with detailed explanations and engaging illustrations, making it easy for independent study. But our digital-age children prefer video learning, right? That's why we included it.
Scan the QR codes located throughout the book.
You can study all concepts from the first to the last unit by watching video lectures.
Check out this delightful, refreshing, and exhilarating lecture from a former EBS math teacher right now!

Great for students like this!

*Friends who are good at finding answers, but don't know the concept when asked about it
*Friends who sometimes get the same type of problem right and sometimes get it wrong

A math book worthy of being called math!!

Mathematics is often said to be beautiful because it presents the necessary truths in a clean, uncluttered way.
We are solving the concept of fractions in the most mathematical way possible.

A book that proves that math books can be pretty too!!!

A math book with a pastel-toned layout that resembles a fairy tale has been published, unfolding mathematical concepts through illustrations.
Add fun to your studies with these pretty math books.
