This article describes a comprehension strategy that can be used by teachers to help students identify and construct the main ideas for expository texts. The BURNS Strategy (i.e., Box. Underline. Reread. Note. Summarize.) was developed as part of a larger reading intervention to improve the comprehension performance of struggling readers in the elementary grades. The BURNS strategy was designed to incorporate thinking scaffolds and question prompts to guide students through a thinking process that might help them construct the main ideas. This article reports on the teaching process and instructional scaffolds used in the intervention, and discusses implications for teaching main ideas in the intervention setting.
