This set includes 26 game pieces with frosted letters, meaning they have a particularly rough surface to touch: the child feels the surface of the letters and memorizes their shape. The game also contains 26 shaped compartments, each of which must be matched to the correct letter of the alphabet based on its initial letter. The frosted letters in italics are a fundamental tool used in Montessori schools for teaching letters to preschoolers. The game is inspired by the principles of Montessori education, including tactile exploration and the ability to control associations during play. Made in Italy.
