Simple and compound sentences worksheets
Third grade worksheets add the classic trap: compound subjects and compound predicates. Ben and Leo share a locker is still a simple sentence, because both boys share one action. Your child labels each sentence, and the trap items are budgeted onto every sheet.
By grade
What students need to know
A simple sentence has one who-did-what. A compound sentence is two of them, joined by a comma and a word like and, but, or so.

Simple and compound sentences across the grades
2nd grade
Simple and compound sentences worksheets for second grade show one sentence at a time to label. Simple means one who-did-what; compound means two, joined by a comma and a word like and, but, or so. The examples stay short, so the two shapes are easy to hear.
3rd grade
Third grade worksheets add the classic trap: compound subjects and compound predicates. Ben and Leo share a locker is still a simple sentence, because both boys share one action. Your child labels each sentence, and the trap items are budgeted onto every sheet.
4th grade
Fourth grade simple and compound worksheets use longer, more natural sentences, so the label has to come from structure, not length. The check stays the same: count the who-did-what pairs and look for the comma plus joining word between them.
