What experiences shape a student's construction of mathematical concepts?

To find answers to these questions, the author interpreted the 2022 revised curriculum achievement standards and selected the experiences students need for each unit.
We present this as an 'experiential standard for learning' and use it as a standard for class design to provide an experience that will help you realize how enjoyable the process of learning mathematics can be.

We created the pimath.kr website to help you experience the various learning activities and tools included in this book more easily and enjoyably.
pimath.kr provides online tools for students to experiment and manipulate the mathematical inquiry activities introduced in the book, as well as video materials to help students understand the inquiry process on their own.
This video will also serve as a good guide for teachers when preparing lessons.
We also hope that sharing and reflecting on our classroom experiences here will lead to the development of better learning materials.

“I believe that for students to enjoy learning mathematics, the most important thing is the experience of discovering and exploring on their own.
So, we've been creating assignments tailored to each student's level, allowing them to explore mathematical principles, define their own definitions, and apply them in practice.
“This book was also written with the hope of helping students experience the joy of mathematics and build confidence.”
