Description: The 'Miracle Hangul Learning' series is a systematic Hangul learning program developed through years of research, practical experience, and scientific testing by Professor Choi Young-hwan, a longtime expert in Korean language education methods. With a carefully curated 35-step learning program and content, each lesson is designed to teach essential concepts efficiently, progressing from easy to difficult. Rather than relying on the traditional whole-word learning method, the series adopts a consonant-vowel-syllable learning approach based on the original principles of Hunminjeongeum, allowing children to master Hangul more quickly and easily. Based on in-depth research into the language acquisition process of four-year-olds, the program incorporates elements that make learning easier and more enjoyable for children, and is designed so that with consistent practice, children can eventually study independently. In addition, as the first early childhood Hangul workbook to include a detailed 'Parent's Guide,' it helps parents carry out structured at-home Hangul lessons with confidence and ease. Based on the fundamental principles of Hangul, the 'Miracle Hangul Learning' series consists of five volumes designed to help children learn Hangul quickly and easily. Step 8: Basic consonant 'ㅅ' (sa, sya, seo, syeo...) Step 9: Basic consonant 'ㅈ' (ja, jya, jeo, jyeo...) Step 10: Basic consonant 'ㅊ' (cha, chya, cheo, chyeo...) Step 11: Basic consonant 'ㅋ' (ka, kya, keo, kyeo...) Step 12: Basic consonant 'ㅌ' (ta, tya, teo, tyeo...) Step 13: Basic consonant 'ㅍ' (pa, pya, peo, pyeo...) Step 14: Basic consonant 'ㅎ' (ha, hya, heo, hyeo...)
