What is Phonological Awareness and Phonemic Awareness?

Phonological awareness is the ability to recognize and manipulate the spoken parts of words. The levels of phonological awareness are, from simplest to most complex: syllables, onset–rime, and phonemes. 

Phonemic Awareness is the ability to identify and manipulate individual sounds (phonemes) in spoken words. We know that a student's skill in phonological awareness is a good predictor of later reading success or difficulty.
