The presenters have been investigating vocabulary in elementary school textbooks to provide useful teaching materials for supporting foreign children in learning Japanese. In this study, vocabulary used in one subject (social studies words /science words) and two subjects (science and social studies common words) were extracted and analyzed for their features. Social studies words are four times more common than science words, but many words are used only once. In both subjects, high frequency words are important for learning subject, but many of them are used as compound words in textbooks, indicating that it is essential to present compound words in textbooks. In addition, although common words are frequently used basic words, their usage varies from subject to subject, making it essential to provide appropriate examples.
