Wooden puzzle for learning numbers

Wooden puzzle for learning numbers Set of 20 puzzles of 2 pieces each for learning numbers and counting. Each pair has written one of the numbers from 1 to 20 and a corresponding number of easy-to-count objects. The puzzles are of the self-correct type, because the cuts of the joints allow only the matching of the pieces that correspond, so that the child can play and learn even by himself. The game helps to learn counting from 1 to 20 and the graphic signs associated with each number in a fun way. The pieces come in a wooden box so they can be stored and kept in order. The durable wooden parts recommend this floor to be used in children's groups: kindergartens, schools, after-school activities. Box dimensions: 35 x 15 x 7.5 cm.
