The wooden Montessori clock with letters is a fantastic educational toy designed to help children learn to read and write 3 letter words. The clock consists of two circles, an outer and an inner circle. The outer circle features one letter on each segment, while the inner circle has two letters on each segment. The set comes with a series of cards featuring pictures and three-letter words. The child can use the cards to match the word to the corresponding letters on the clock. By placing the card on the clock, the child can then repeat the word, practicing pronunciation and spelling.
