Sound Substitution Words Worksheet
This worksheet practices sound substitution by changing the last sound of each word to make a new word, like pig to pie and cow to cog.
Sound substitution matters a lot for 1st grade because ending sounds affect spelling and decoding. Many kids get stuck when the first part feels right, but the last sound gets skipped or rushed.
Use the page together like this: say the starting word, have the child repeat the word, then choose one new last sound, and read the new word out loud before writing or underlining.
The worksheet helps children focus on one specific sound change, not a pile of mixed tasks. Each row gives quick feedback by turning one word into another clear match.
