A hands-on language tool rooted in the Montessori method, this moveable alphabet set includes lowercase wooden letters in color-coded red (consonants) and blue (vowels), a compartmented storage box, and a large work mat. Children arrange the letters to build words, phrases, and eventually sentences — developing phonics, spelling, and early writing skills long before they've mastered pencil and paper. It's a staple of Montessori classrooms and homeschool settings.
