This second Medium worksheet focuses on the tricky difference between a topic and a main idea. Fill-in-the-blank questions guide second graders to see that a topic is one or two words while a main idea is a full sentence telling something about that topic. A matching section pairs single-word topics like Spiders, Seasons, Teeth, and Pets with full main idea sentences, sharpening the skill of expanding topics into complete ideas.
