This Easy level worksheet introduces second graders to main idea and supporting details through gentle practice. Students sort six sentences into "About Penguins" and "Not About Penguins" to see how details connect to a topic. A fill-in-the-blank section teaches key vocabulary like main idea and supporting detail, and a true or false section checks understanding of where the main idea usually appears in a paragraph and how details work.
