Teacher's field guide

What Students Need to Do: Students listen to a word and add one sound in a named spot. They say the new word without leaving out any of the original sounds.
What Mastery Looks Like: A student can add /s/ before “top” and say “stop.” They can add /s/ after “lip” and say “lips.”
Common Misconceptions: Some students say the letter name “ess” instead of the sound /s/. Others replace a sound instead of adding one, or put the new sound at the wrong end of the word.
How to Assess It: Say “top” and ask, “Add /s/ at the beginning. What word do you get?” Then say “lip” and ask students to add /s/ at the end.

Lesson moves

Give students counters for the sounds in “sat”; have them slide in one counter for /l/ after /s/ and say “slat.”
Ask, “What happens when you add /s/ before ‘top’?” Have partners say both words and name the added sound.
Play picture bingo: say “lip,” ask students to add /s/ at the end, and have them cover a picture of lips.
Show a grocery tag for rice; add /p/ before “rice” to make “price,” then point to the price on the tag.
