Description 1. Numbers up to 9 2. Various Shapes 3. Addition and Subtraction 4. Comparing 5. Numbers up to 50 Feel math! This is another must-have book on the path to becoming a top-tier math student. Choisangwi Math S helps children build a genuine feel and understanding for math, empowering them to solve any problem and develop the strength to remain in the top tier all the way through middle and high school. By covering not only textbook concepts but also advanced concepts, this book helps children build a solid foundation for deeper learning. Through visual images, learners can intuitively feel and understand the core of advanced concepts. The book reflects the new curriculum, strengthening core academic competencies and carefully structuring difficulty levels and problem sets so that every child has the chance to reach the top tier. With a companion review book that matches the main text problems one-to-one, children can repeatedly practice and build advanced mathematical thinking skills from an early age.

✐ Basic Concept Covers not only textbook concepts but also advanced concepts and concepts that connect to future grades, allowing children to build a strong foundation for advanced learning through related practice problems. ✐ Choisangwi [S] Through a combination of "one sentence + image," children can intuitively feel and understand the algorithm and core concepts needed to solve advanced problems. Based on this understanding, they solidify top-tier skills by solving similar problems. ✐ Math Master Beyond typical advanced problem types, this section offers a variety of challenging and competition-level problems, encouraging children to aim for the top 3%. Includes a one-to-one review of all representative problem types from the main text and the Math Master section.
