Building compound sentences: a complete guide for Grade 3 students

📚 What is a Compound Sentence?

A compound sentence is like a super-sentence! It's made up of two or more simple sentences (also called independent clauses) joined together. These simple sentences each have their own subject and verb, and they can stand alone as a complete thought. When we combine them, we need a special connector: either a coordinating conjunction (like 'and', 'but', 'or') with a comma, or a semicolon (;).

🗓️ A Little History

People have been combining sentences since... well, since people started writing! The idea of formally recognizing compound sentences probably came about as grammar rules became more structured. Think of early storytellers linking ideas to make their tales longer and more interesting. It's been happening for ages!

🔑 Key Principles for Building Compound Sentences

• 🤝 Independent Clauses: Each part of the sentence needs to be able to stand alone. Think of them as complete thoughts.
• 🧲 Coordinating Conjunctions: Words like 'and', 'but', 'or', 'so', 'for', 'nor', and 'yet' help connect the clauses. Remember to use a comma before the conjunction!
• ➡️ The Comma Rule: Always place a comma before the coordinating conjunction (unless you're using a semicolon).
• 🔀 The Semicolon Option: You can also use a semicolon (;) to join two closely related independent clauses without a coordinating conjunction.

✍️ Real-World Examples

Let's look at some examples of how compound sentences are used every day:

1. I wanted to go to the park, but it started to rain.
2. She likes to read books; her brother prefers to play video games.
3. We can eat pizza, or we can have tacos for dinner.
