“Em học Việt ngữ – Lớp Tư” ( I Learn Vietnamese, Grade Four), published in 1969 by the Ministry of Culture and Education of the Republic of Vietnam, was the official instructional material for Grade Tư in primary school, equivalent to today’s second grade. Each lesson not only focuses on vocabulary building and reading comprehension, but also connects to real-life experiences familiar to children in Southern Vietnam during that period. With diverse learning formats—such as storytelling, role-playing, gestures, singing, and games—the book helps children retain vocabulary and sentence structures in a natural and engaging way. The textbook comprises 64 lessons, organized into 8 chapters, gradually introducing topics such as Home, Family, Food, Clothing, Body, Animals, School, and Play, following the developmental journey of the main character Nhơn, a 7-year-old second-grade student.
