Teacher's field guide

What Students Need to Do: Students listen to a word like cat and turn it into bat, cut, or cap by changing one sound. They keep the other sounds in place.
What Mastery Looks Like: Given cat, a student can say bat when the first sound changes to /b/, cut when the middle sound changes to /ŭ/, and cap when the last sound changes to /p/. They can tell which sound changed.
Common Misconceptions: Some students say “bcat” when asked to change /k/ to /b/, adding a sound instead of replacing one. Others change the first sound when asked to change the last, or name letters instead of saying sounds.
How to Assess It: Say, “Start with cat each time. Change the first sound to /b/, the middle sound to /ŭ/, and the last sound to /p/.” Listen for bat, cut, cap.

Lesson moves

Place three counters for the sounds in cat; call out “first to /b/, middle to /ŭ/, last to /p/,” resetting and saying each word.
Ask partners, “If cat becomes cap, which sound changed, and which sounds stayed the same?”
Play sound-swap bingo: say, “Change the first sound in map to /t/,” and have students cover tap on their boards.
Show a sample name tag for Sam; switch /s/ to /p/ aloud, then have students make a new tag for Pam.
