Wink Korean is structured into 5 levels. Level 1 is a 'picture word' (whole-word) approach where children learn the names of objects around them as words. Level 2 focuses on the shapes, names, and combinations of consonants and vowels. Level 3 begins formal single-word writing practice. Level 4 helps them learn sentence structure and build sentences. Level 5 is an advanced stage where they learn sentence composition and logic, transitioning to more complex writing.
