Sound Substitution Last Sound Word Changes

This reading and writing worksheet practices sound substitution by changing the last sound in each word to make a new word, like pig to pie or cow to cog.

At age 7 and up, first graders often get stuck when letter shapes feel more important than sounds. Sound substitution helps your child hear and write word parts with more confidence, especially when the last sound feels tricky during reading or spelling.

Use this exact page for a quick, screen-free shared practice: say the starting word, cover the rest of the word with a finger, then ask for the new word by changing only the last sound. After the child answers, have the child repeat both words out loud so the sound swap feels clear.

The worksheet stays focused on one small rule, changing only the final sound, so progress feels steady. Each completed word match connects speaking, listening, and early decoding, which makes it more targeted than a generic word list.
