Writing Sentences Using Sounds

This lesson shows how to listen for sounds in words, spell those words with the matching letters, and then put the words together into a short, complete sentence with a capital letter, spaces, and an end mark.

Introduction

You already know that letters make sounds. Now you can use those sounds to spell whole words, and then put words together to write a full sentence. A sentence is more than one word. It tells a whole idea, like "I see a cat." This lesson shows you how to sound out words and line them up to write sentences that other people can read.

Sounding Out Words to Spell Them

Before you write a word, say it slowly and listen to each sound. The word "sun" has three sounds: /s/, /u/, /n/. Each sound matches a letter. You write S for /s/, U for /u/, and N for /n/. When you stretch out a word like this, spelling gets much easier.

Try this with more words. The word "hop" has the sounds /h/, /o/, /p/. The word "fish" has the sounds /f/, /i/, /sh/. Notice that two letters, S and H, work together to make one sound, /sh/. Listening carefully helps you pick the right letters every time.

Turning Words Into a Sentence

Once you can spell single words, you can put several words together to make a sentence. A sentence tells a full idea, not just one thing. "Cat" is a word. "I see a cat." is a sentence because it tells what is happening.

To write a sentence, sound out each word one at a time and write it down. Then leave a small space before you start the next word. Say your sentence out loud first, so you know what to write. For example, say "The dog runs," then sound out and spell "The," then "dog," then "runs."

The Parts Every Sentence Needs

A finished sentence has three important parts. It starts with a capital letter. It has a space between every word. It ends with a mark, like a period, so the reader knows the sentence is done.

Each word gets its own box, a space sits between words, and a period ends the sentence.

Missing any of these parts makes a sentence harder to read. Check your own writing by asking three questions. Does it start with a capital letter? Is there a space between every word? Does it end with a period, a question mark, or an exclamation mark?

Try It: Write Your Own Sentence

Say this idea out loud: "The pig is big." Now sound out and spell each word one at a time. /Th/ /e/ for "The." /p/ /i/ /g/ for "pig." /i/ /s/ for "is." /b/ /i/ /g/ for "big." Write a capital T to start, add a space after each word, and put a period at the end. Your finished sentence reads, "The pig is big."

Now try it yourself with a new idea, like "My cat can run." Sound out each word, spell it, add spaces, and finish with a period.
