Solve It Yourself! Math Word Problems
I can solve descriptive sentence problems by myself!
An important step in the new curriculum: follow along and you're done!

■ New textbooks emphasize descriptive and problem-solving processes in elementary mathematics assessments
The core of the newly revised curriculum is 'cultivating talent fit for the era of the Fourth Industrial Revolution.'
Therefore, the new curriculum will focus on assessments that are centered on self-exploration and learning, rather than the simple memorization of the past.

A representative type of process-oriented evaluation is descriptive.
In mathematics, there are more sentence-type problems related to real life than simple calculations, and the weight of evaluating the 'solution process' as well as the answer has increased significantly.

■ The process is more important than the correct answer! ― The sentence-based solution process is fully reflected!
Under the new curriculum, multiple-choice tests have been eliminated from elementary schools in Busan.
Subjective exams are also increasingly written in descriptive form, and the proportion of questions that require explanations is also increasing.
"I Solve It Myself!" Math Word Problems faithfully reflects the educational goals of the new curriculum! We carefully selected only the appropriate difficulty level for the new textbook and implemented a step-by-step solution process to help children complete the solution process independently.


■ Don't study sentence problems as hard as you used to!
Solve it on your own! Math word problems are new textbook-style word problems that you can easily practice on your own.
This book doesn't have the useless, twisted questions of old-style books or the problems designed to knock out children like those in competition preparation books.
This is a sentence problem book designed to help you build your skills and study effectively.
Additionally, it is structured to be easily solved in the order of the thought process, rather than in a difficult way of breaking down and analyzing the problem itself.
From short answer questions to descriptive questions, we gradually increased the number of blank spaces and structured the questions so that students would write down the solution process and answers.
These days, it's a school exam-style sentence problem, so any 5th grader can easily try it.

■ I don't understand what the problem is.
― You gain the power to understand the problem!
The biggest reason for making mistakes on word problems is because you read the problem roughly or, even if you read it, you don't understand it well.

Solve it yourself! Math word problems train you to read the problem clearly by circling the numbers and underlining the answer (usually the last sentence).
If you develop the habit of reading problems accurately, you will gain the ability to quickly understand the given conditions and what is being sought.


■ Come up with your own problem-solving strategy! ― Post-it notes and sketchbooks
This book presents Post-it notes and a sketchbook to help you find problem-solving strategies.
Feel free to organize your thoughts as if you were doodling—drawing tables, pictures, or simply expressing them! You'll discover your own problem-solving strategies!

■ Don't be confused! - Practice the solution process by filling in the blanks!
Once you understand the problem, you need to set up an equation and find the answer.
This book is structured so that by filling in the blanks in the solution process, the equations will be completed and the answers will be found.
Additionally, the first type of solution process is structured to follow the light text, preventing you from getting lost.

Also, by following the blanks in this book and filling them in, you will become trained in the problem-solving process, and you will gain the ability to write long solution processes on your own.

Math is effective when you start with problems that can be solved with just a little effort.
Solve math word problems on your own, at a level of difficulty that's neither too difficult nor too easy.
As you solve problems on your own, you will gain confidence in math and at some point your mathematical thinking skills will improve.
The problem-solving skills developed this way will give you the power to solve any math problem!

■ During the semester, follow the textbook progress, and complete it in a short period of time during vacation!
1.
How to study according to the textbook progress during the semester?
"I Solve It Myself! Math Word Problems" covers every chapter of the revised textbook.
And I've collected the essential sentence problems from the textbook.

It is structured so that you can understand on your own by solving basic problems that confirm textbook concepts and practice book word problems in order.
After studying the entire unit, you can prepare for the school unit tests with the 'This is how the unit test is done!' corner!
If you study with the textbook and try out the "I Solve It Myself! Math Word Problems" challenge, the concepts will be reviewed naturally.
Make a plan to study 2 pages a day, 4 times a week.

2.
Want to study during vacation?
If you study with a general workbook during the semester, try previewing or reviewing with this book during vacation.

Rather than simply practicing word problems, all courses in the first semester are arranged in order of difficulty, allowing you to progress smoothly while gaining a richer understanding of the subject matter!
Try studying one lesson a day.
You can cover one semester's worth of math in one month.
