An "ABC Book" is a type of children's book designed to teach the alphabet. Each page typically features a letter from A to Z, accompanied by illustrations and words that start with that letter. For example, the letter "A" might show an image of an apple, while the letter "B" could feature a ball. This format helps young readers associate letters with sounds and words. These books often use colorful pictures and simple text to engage children and make learning fun. Many ABC books also include interactive elements, such as flaps or textures, to enhance the reading experience. They are commonly used in early childhood education settings to support literacy development.
