Punctuation

Grade 7 · English Language Arts · Free lesson

Hi there! I'm Studyfin, your learning buddy. Let's explore how punctuation acts like traffic signs for your sentences!

Every sentence needs a clear ending so the reader knows when to pause. A period shows a complete stop. When you edit your drafts, always check that your complete thoughts end with a period.

A comma acts like a yellow traffic light. It tells the reader to slow down and take a quick breath, but not to stop completely. We use commas to separate items in a list, like apples, bananas, and cherries.

My grocery list: Apples , bananas , and grapes.

When we edit drafts, we must analyze how ideas connect. If you join two complete thoughts with just a comma, it creates a 'comma splice' error. To fix this, we can add a coordinating conjunction like 'and' or 'but' right after the comma.

✏️ Worked example

Edit the following draft to fix the punctuation: "The sun was shining bright, we decided to go to the park."

  1. Read the sentence aloud to find the two complete, independent thoughts.
  2. Identify thought one: 'The sun was shining bright' and thought two: 'we decided to go to the park.'
  3. Notice that only a comma joins these two complete thoughts, which creates a comma splice error.
  4. Choose a method to fix the splice. You can change the comma to a period, or you can add a coordinating conjunction like 'so' after the comma.
  5. Rewrite the corrected sentence: 'The sun was shining bright, so we decided to go to the park.'
