Set out your lesson
“Many short words split into an onset and a rime. The onset is the first sound. The rime is the chunk that starts with the vowel. We can blend them, pull them apart, and swap one sound to make a new word.”
Bring to the table
- Ready onset cards: c, b, d, m
- Ready rime cards: at, og, ap
- Paper and marker only if a card needs rewriting
Full guide and materials
- Ready onset cards: c, b, d, m
- Ready rime cards: at, og, ap
- Paper and marker only if a card needs rewriting
- Step 1. Model blend: put c with at and say /k/…/at/… cat.
- Step 2. Have your child blend b+at → bat and d+og → dog.
- Step 3. Say cat slowly. Ask for the first sound (/k/), the middle sound (/a/), and the last sound (/t/).
- Step 4. Start with cat, swap the first sound card from c to m, and blend mat.
- Step 5. Let your child choose one onset and one rime, blend the word, then change either the onset or the final sound to make a new real word from the same cards.
- Quick check. Success means your child (1) blends one onset+rime into a whole word, (2) names the first, middle, or last sound in a CVC word you say, and (3) changes one sound to make a new word.
Worked example. c + at = cat. Change the onset to b → bat. d + og = dog. In dog, first=/d/, middle=/o/, last=/g/.
Optional challenge. From tap, make two new words: change the first sound once and the last sound once, saying each full new word.
What to notice. Save a parent note with the blend, the sound-position answer, and the new word your child made.

Many short words split into an onset and a rime. The onset is the first sound. The rime is the chunk that starts with the vowel. We can blend them, pull them apart, and swap one sound to make a new word.
Spend about 10 minutes blending and swapping with the supplied onset and rime cards only.

Check understanding
- 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')
“If you slowly say the sounds '/d/ /o/ /g/', can your child blend them together and say 'dog'? And if you say 'cat', can they tell you the three separate sounds: /k/ /a/ /t/?”
