Abstract: An educational device, such as a book, is designed to help children learn to read using building blocks of the English language, such as "tri-gram", composed of a consonant, followed by a vowel, followed further by another consonant. The book has a plurality of pages, wherein each page includes a plurality of partial page portions, preferably three, which can be independently turned from either of the other two partial page portions. The partial page portions are separated from each other by incisions, so that the partial page portions can be turned independently from the other two partial page portions. Each partial page portion includes a turnable picture and letter card with a consonant on the left-hand partial page portion, a vowel on the middle page portion, and a second consonant on the right-hand side page portion. Therefore, a child can make many pronouncable syllable words, such as "cat," "pet," "run," etc, with a selected array of the partial page portions.
