What This Standard Means
What Students Need to Do
- Students listen to one-syllable words and split each into the beginning sound or sound group and the rest of the word. They also combine two spoken parts to say a whole word.
What Mastery Looks Like
- A student can hear /m/ and /ap/ and say map without adding extra sounds. Given fish or stop, the student can say /f/ and /ish/, or /st/ and /op/.
Common Misconceptions
- Some students split every sound, saying /s/ /t/ /op/ instead of /st/ /op/. Others add an extra vowel sound, such as /muh/ for /m/. Some give a rhyming word instead of splitting the word they hear.
How to Assess It
- Say, "What word do /s/ and /un/ make?" Then show a picture of fish and ask, "Say fish in two parts."

Ways to Teach It
Give each student two counters, say a word, and have them push one counter for the onset and one for the rime.
Ask which part sounds the same in sun, run, and fun, then have partners say each word in two chunks.
Play Mystery Word: say an onset and rime, and students cover the matching picture on a bingo board.
Students find a one-syllable classroom object, name it, then say its beginning chunk and remaining chunk to a partner.
