Description
Book Introduction
A new concept in elementary math that develops real math skills.
● Learn with textbooks for each grade level.
(3rd and 4th grade elementary school)
Basic Math for Life and Science Volume A is one of Wind Edu's 'Elementary Math for Life and Science Series', and is a new concept textbook that completely restructures the elementary curriculum to develop number sense and mathematical thinking skills.
This book is a new concept learning book that focuses specifically on the 3rd and 4th grade elementary school curriculum, and is designed to be most effective when used alongside basic textbooks for each grade.
● Mathematical thinking skills cannot be developed through vertical arithmetic alone.
Operational learning centered on vertical arithmetic only involves repeating the process of finding the correct answer, which limits the development of children's thinking skills and creative problem-solving abilities.
On the other hand, since the horizontal operation is expanded by spreading the equation out sideways, the principles of the four basic arithmetic operations, such as the distributive law and the commutative law, and the structure of the equation are clearly revealed.
Through this, children can observe the characteristics of numbers and formulas, and develop mathematical thinking by solving the same problems in various ways.
● A textbook that can help you develop real computational skills
[Learning various methods of number decomposition]
It covers decomposing a number in several ways (e.g. using digits, using number patterns, using subtraction).
This fosters a deep understanding of the nature of numbers and the ability to manipulate numbers from various perspectives.
[ Crosswise operation ]
Focuses on helping elementary school students improve their number sense and effectively learn cross calculations.
Visualizing Mathematical Concepts
Visual learning using number lines helps you clearly understand abstract concepts such as number ranges and estimation.
[Concept Summary]
We support the process of understanding and internalizing core concepts through concept learning that organizes mathematical concepts into a single sentence and a concept organization corner where students can organize them on their own.
[Expansion of the formula and reconstruction of the calculation formula]
'Familiarity Problems' provides practice in handling the computational process flexibly beyond simply finding the answer, such as expanding equations and reconstructing calculation formulas.
[ Cultivating mathematical literacy ]
We provide a variety of application problems to help you develop mathematical literacy through 'sentence problems'.
This develops the ability to apply mathematical concepts in real-world problem situations.

Publisher's Review
This book is designed to go beyond simply developing computational skills and help our children develop mathematical thinking skills and a deeper understanding of the nature of numbers.
Many children who become accustomed to only vertical arithmetic operations often struggle to solidify the basic concepts of operations by focusing only on the calculation method.
Accordingly, we focused on enabling children to learn the principles of arithmetic operations by observing them as they unfold the problem-solving process.
In particular, through a unique approach of number decomposition and cross-section operations, it guides you to intuitively understand how numbers are composed and how operations work.
[Author's Note]
When we see children learning arithmetic, they often only diligently repeat vertical arithmetic.
Learning accurate calculation methods is important, but doing so alone will not develop your mathematical skills and critical thinking abilities.
Because mathematics is not simply the art of finding answers, but the process of understanding how numbers and formulas are created and connected.
So, in this book, we use number decomposition and cross-referencing to show you the calculation process with your own eyes and to solve the same problem in various ways.
I hope that through these experiences, children will gain a deeper understanding of operations and experience the joy of figuring out for themselves why things happen this way.
I hope this book will help children develop real mathematical skills.
