This medium worksheet asks kindergartners to think about size: which part of a story is biggest, and which parts are small. Young learners fill in nine sentences about how the main idea is the biggest part, how details are the small parts, how a story about the park has the park as its topic, and how finding the main idea helps you understand a story. The matching section then pairs school with "Kids learn to read," the farm with "Cows eat hay," the zoo with "Lions roar loud," and winter with "Snow falls down."

Sorting big ideas from small details with familiar settings builds the habit kindergartners will use when they read longer paragraphs in first grade.
