Sentence Detective: Simple, Compound, or Complex Sentences Worksheet for Kids
This worksheet introduces children to three different sentence structures, simple, compound, and complex, teaching them to notice how conjunctions and clause combinations change a sentence's complexity, a more advanced grammar concept appropriate for ages four to six who are already reading independently. Recognizing these structures also improves reading fluency, since children start to anticipate pauses and connections within longer sentences.

How to use this worksheet
Read the example sentences at the top of the page together first, discussing what makes each one simple, compound, or complex. Read each practice sentence aloud with your child, looking for clues like conjunctions ('and,' 'but,' 'because') that signal a compound or complex structure. Have your child write their answer, simple, compound, or complex, on the line provided for each sentence. Review their answers together, asking them to point out the specific word or clause that helped them decide.
