Combine Sentences With Conjunctions Worksheet Grade 3

About this worksheet

Eight pairs of short sentences, each to be joined into one using and, but or so. I have a bike. I have a scooter. Tia likes math. She does not like spelling. The rain stopped. We went outside.

This is the step from choosing a conjunction to using one. A child has to write the whole new sentence, which brings in the comma before but and so and the chance to drop a repeated word, turning Max fed the fish. He cleaned the tank. into Max fed the fish and cleaned the tank.
