Learn to Capitalize Sentences and the Pronoun I!

Every time you write a sentence, you start with a big letter. You also always write the word "I" as a big letter. These are two very important writing rules you will use every day!

When you learn to capitalize the first word in a sentence, your writing looks right and is easy to read. Big letters help people know where a new sentence begins.

The very first word in every sentence gets a big letter at the start. For example, "The cat is soft" starts with a big T. You always make that first letter big!

Look at this: "my dog is fun" is not right. "My dog is fun" is correct because M is big. You can practice this every time you write.

The word "I" is special. You always write it as a big letter, even in the middle of a sentence. "I like cats" and "My mom and I play" both use a big I.

It does not matter where "I" is in your sentence. It is always big! This is one of the most important writing rules you will learn.
