The Clementoni Education Montessori Tactile Numbers set is a tactile perception-based game for teaching numbers according to the Montessori method. The set includes 10 cards with embossed numbers and a special textured finish, which the child explores with their fingers to memorize the shape of each number before moving on to associating them with quantity cards. The game also allows children to write numbers on a chalkboard and distinguish even from odd numbers, stimulating numerical thinking in a sensory and progressive way. This multisensory approach is especially effective for reinforcing basic mathematical concepts at a stage when the child is still developing fine motor skills. It is recommended for children from 3 years old, always with adult supervision.
