Four Corners/Jig Saw

Four Corners/ Jigsaw organizes students into subgroups to focus on one aspect of a learning unit, then brings them together as a full group to report and compile the information gathered. This strategy is especially effective in analyzing a collection of primary sources—such as an object, a photograph, and a document—that all relate to each other. By focusing on one primary source and then adding information about the others, students come to understand the strengths and limitations of various types of evidence and the necessity for corroboration.
