Phonemic awareness refers to the ability to segment and manipulate the sounds in spoken language and is a predictor of reading success. It is distinct from phonics which relates letters to sounds. There are 7 dimensions of phonemic awareness including identifying syllables, rhyming words, and blending/segmenting sounds. Educators can scaffold phonemic awareness through choosing books with rhyme and repetition and activities like word games. Progress is assessed through tools like ISEL which measures phonemic awareness, letter knowledge, and sounds.
