· This is a good math word problem book that helps me solve problems on my own.

'I'm Busy Solving Math Word Problems on My Own' is a book created with the goal of finding ways to solve math word problems as easily as solving calculations.
Parents who have already experienced this book have been impressed, saying, "This is a great workbook that explains difficult concepts in an easy-to-understand way!" and "My child is satisfied with the easy-to-understand explanations!"
This book uses a "small-step" approach to structure the problems, gradually increasing the level of challenge.
From short answer questions that anyone can easily challenge to word problems for school exams, we've gradually increased the number of blanks and structured the questions so that you can write down the solution process and answers.
Children experience a sense of accomplishment as they solve problems on their own, which can increase their interest in math.

· Math requires time to solve problems alone!

Math requires time to solve problems alone.
Just as you won't develop muscle strength if someone else helps you with exercise, you won't develop thinking muscles if you listen to your parents' explanations while solving problems.
However, if the problem is too difficult, children will have a hard time solving it on their own.

"I'm Busy Solving Math Word Problems on My Own" is a book that is organized step-by-step, from easy-to-solve basic word problems to modern school exam-style word problems, allowing children to challenge themselves and experience accomplishment.
The sentence structure requires careful consideration and the mindset to solve at least one problem correctly.
Don't ask your parents to solve it for you! Even if it seems frustrating, just wait a little. Solving problems on your own will build your confidence in math, and you'll even see improvements in your mathematical thinking skills.
The problem-solving and mathematical thinking skills developed this way will become a stepping stone for doing well in higher grade math!
