Graphic organizers are generally used during the Guided Reading Block as a Pre-reading/Post Reading activity. In Guided Reading, graphic organizers establish prior knowledge, activate schema, help students in making predictions, and assess students' comprehension. Graphic organizers provide a visual connection with the text and explicit guidance in note-taking and classifying information for recall. For this reason, graphic organizers are particularly effective with content area or expository text.
Also used in the Writing Block, graphic organizers help students plan for writing. Graphic organizers provide a visual framework for details, comparisons, sequences, and interactions.
