Sound Substitution Last Sounds Worksheet

Say a short word, change one sound, and listen to the new word. This last-sound substitution worksheet pairs written starting words with replacement-letter cues and spaces for new words. The five changes are cat to cap, fan to fat, pen to pet, pig to pin, bag to bat. Use the page with an adult who can model the sounds and help with writing, keeping each spoken change clear before moving to the next row.

Begin with cat. Read it aloud, then point to the letter p in the cue column. Model the sound that letter represents in cap, replace the last sound, and blend the new word. Say cat and cap again so your child can compare them. Write cap in the answer space after the spoken change makes sense.

Try fan to fat next. Keep the other sounds in place while changing the last one. If the task feels difficult, use three counters to represent the spoken sounds and replace only the counter in that position. The oral version practices phonemic awareness. Connecting those sounds with the printed letters adds phonics practice; an adult can handle the writing while the child concentrates on listening and speaking.

Work through one or two rows, then return to the others when your child is ready. Read a completed pair and ask what changed, giving a model again when needed. The Phonics and Sounds set offers related letter-and-sound activities. For a later writing task, explore the Spelling and Word Building set. Choose the next exercise according to the support your child needs with sounds, letters, or spelling.
