Onsets & Rimes

English · Phonics & Word Reading · procedural

Blend and segment onsets and rimes in single-syllable words; isolate and pronounce individual phonemes (initial, medial, final) in CVC words; add or substitute phonemes to make new words

What mastery looks like

  • Blend onset and rime to say a word (e.g. /c/ + /at/ → 'cat')
  • Identify the first, middle, or last sound in a CVC word
  • Change one sound to make a new word (e.g. change /c/ in 'cat' to /b/ → 'bat')

Check your understanding

If you slowly say the sounds '/d/ /o/ /g/', can Onsets & Rimes blend them together and say 'dog'? And if you say 'cat', can they tell you the three separate sounds: /k/ /a/ /t/?
