Sound Substitution Word Change Worksheet

This worksheet helps kindergarten kids practice sound substitution, changing the first sound of each word to make a new word. Example pictures and words support changes like dog to cog and cat to hat.

First-sound swapping matters because it connects listening to reading and spelling in a way that makes sense early. Many parents notice their child gets stuck when letter-shape work feels slow, or when the task seems like it has to be done perfectly.

Use this exact page by choosing one row. Read the first word together, say the first sound out loud, then guide the sound change. Have the child point to, or write, the new word created by that first-sound swap.

Each answer depends on hearing and changing only the first sound, so the activity feels focused instead of random. The pictures and repeated pattern make it easier for a child to try again, without turning the whole session into a big reading test.
