This is a strategy to teach students how to summarize any text. Using this Triangle Summary graphic organizer, students can visually see how the information builds on each part to create a summary. We can't just assume students truly know how to write a summary. As text levels increase, sorting through the information to find the main idea and supporting details gets more difficult. This is a way to explicitly teach students how to write a summary and include details that actually support the main idea not just random facts from any level of text.
The first triangle is an example to refer to & model with students how information is organized in a summary. The blank triangle can then be used with any text after they understand how to fill it in...they will need practice from short texts in any content area.
Students learn to identify parts of a summary and put them all together to create a strong summary:
Topic + Main Idea + Supporting Details = Summary
My students have found it helpful to put the blank graphic organizer in a plastic sheet and reuse when they need to to help them organize their ideas before they write a summary of a text.
