Sound Substitution Last Sound Word Builder Worksheet

English Sound Substitution Phonological Awareness 5 years old

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, sun to sub, fan to fat, pen to pet, pig to pin. 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 sun to sub 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.

Frequently asked questions

Which word changes are included?

The five pairs are cat to cap, sun to sub, fan to fat, pen to pet, pig to pin. Each row provides a starting word, a replacement-letter cue, and space for the new word.

How do we begin the last-sound change?

Say cat, model the sound represented by p in cap, and replace the last sound. Blend and say cap before writing it.

Is this phonemic awareness or phonics?

Changing sounds in spoken words practices phonemic awareness. This page also connects the sounds with written letters, so that part of the activity is phonics. You can try the spoken change first with the writing covered.

What if handwriting distracts from listening?

Let the child say the change while an adult writes the new word. Three counters can stand for the spoken sounds; replace the counter in the target position and blend again.

Should my child finish all five rows?

Begin with one or two successful examples. Revisit the remaining rows later, modeling the starting word and replacement sound whenever the child needs another demonstration.
