Phonemic awareness is PART of phonological awareness. Phonemic awareness is the highest level - where we distinguish the smallest units of sound - or phonemes.

Notice that the little girl is blindfolded? That's because she doesn't need to see anything to engage in the work of phonemic awareness! Phonological and phonemic awareness, in their purest forms, do not involve print. So, students don't need letter tiles, flash cards of words, or reading passages to manipulate sounds. They just need to be able to listen, hear, and do!
MANIPULATING involves isolating, blending, stretching, segmenting, substituting, and deleting sounds.
To best help our students with phonemic awareness, we need to be good models for producing the sounds ourselves.
