Grade 4 students practice the comma rule with FANBOYS conjunctions: for, and, nor, but, or, yet, so. They learn to add a comma before the conjunction when it joins two complete sentences and to skip the comma when it joins only two short items. Sentence corrections, fill-in-the-blank items, and short answers reinforce when commas are needed and when they are not, using familiar Grade 4 contexts like picnics, hiking, and bake sales.

2. The sky grew dark and the wind picked up before the storm.
3. I wanted to swim, but the pool was already closed for the day.
4. Mom baked cookies and muffins for the bake sale.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Write a compound sentence about a rainy day using a comma and a FANBOYS conjunction.
The rain poured all morning, but the sun came out by lunchtime.
2. Explain when you do NOT use a comma before a FANBOYS conjunction.
You do not use a comma when the conjunction joins two short items or phrases instead of two full sentences, like apples and oranges.
