Phoneme & Letter-Sound Ladders
One of the most well-established findings in beginning reading research is the relationship between phonemic awareness and reading acquisition. Phonics is the system by which symbols (i.e., letters, also called graphemes) represent sounds (i.e., phonemes) in an alphabetic system like English. Some sounds are represented by just a single letter (e.g., b for /b/ as in tub) while some sounds are represented by two or more letters (e.g., bb for /b/ as in rubber). In order to learn this phonics system where "print maps to speech" students rely on their phonemic awareness ability to isolate, blend and segment sounds as they learn which letters/graphemes represent those speech sounds. This is why, of all the phonological awareness tasks, phonemic awareness is most closely associated with phonics and learning to read. One activity that can support both phonemic awareness and learning letter-sound correspondences is Word Ladders, sometimes called Word Chains.
