Learn non-fiction reading and 4th grade science at the same time.

Reading comprehension is essential for understanding course concepts.
As you read, interpret, combine the information contained within, and master the concepts, your understanding of the subject matter will naturally increase.
You can broaden your understanding by easily and naturally learning the concepts hidden in the text.

Intensive non-fiction reading training with texts related to scientific principles

Learning science through concepts alone is boring.
We present texts based on scientific principles that children will find interesting, and present curriculum concepts related to the phenomenon.
It is structured so that students can learn the concepts naturally by finding related concepts in the scientific principles presented in the text.


Effectively understand science curriculum concepts through background knowledge

The science concepts learned in each grade are organized into text and pictures to help students understand them effectively.
You can understand the concepts related to the text at a glance through images that concisely present the concepts of the subject, and you can study in depth by reading texts that explain the concepts of the subject.
