Sound Substitution Word Change Worksheet
The sound substitution worksheet asks a child to change the middle sound of each word to make a new word, like bull to bell and horse to house.
At age 6, kindergarten readers often recognize whole words, then stall when a single sound changes inside the word. Sound substitution helps children hear the “middle” and swap it on purpose, not guess. When practice turns into letter-shape work, kids can tune out fast, so this worksheet keeps the focus on sound changes.
To use this page, pick three word items, say the first word together, then change only the middle sound and blend the result. Have the child write the new word in the space on the worksheet, and use one finger tap for each sound swap.
This page is useful because each item trains one clear skill, middle-sound replacement, without mixing in lots of other tasks. The quick word changes make shared practice feel doable, and the results are easy to check right on the page.
