Alphabet blocks are colorful wooden or plastic cubes that feature letters of the alphabet on their sides. They are often used as educational toys for young children to help them learn the letters and improve their spelling skills. Each block typically displays a different letter, and some may also include pictures or numbers. These blocks can be stacked, sorted, and arranged, making them a fun way for kids to engage in hands-on learning. Playing with alphabet blocks encourages creativity and fine motor skills, as children manipulate the blocks to form words or build structures.
