Main Idea Anchor Chart (4 Printable Charts, PDF)

About this resource

What's inside this resource

Two anchor charts teach students how to identify the main idea of an informational text, each provided in a fully completed poster version and a blank fill-in-the-blank version for interactive notebooks. The first chart pairs a simple main-idea-and-detail graphic organizer with the sentence frame 'The main idea of this text is ___. I know this because ___,' prompting students to state and support a claim about a text's central idea. The second chart walks through a before/during/after reading strategy — previewing the title and pictures before reading, watching for repeated key words during reading, and asking 'What is this text mostly about?' after reading. Both charts print a standards code (RI 1, 2, 7, 8) and are sized for classroom display or for gluing into students' reading notebooks.
