My Letters in Stories series: It is a collection of 28 stories, with the number of letters of the alphabet. Each story focuses on one of the letters, as this letter appears in a different color than the rest of the letters. It also indicates the shape of the letter, whether at the beginning, middle or end of the word, which makes it easier for the child to distinguish between the same letters and the forms of the single letter that differ according to its position in the word.
