This lesson supports students' exploration and understanding of the purposes for section headings in expository texts. Working together, students read expository texts and insert the missing section headings. This lesson provides guided practice for students as they discuss how section headings are used to enhance comprehension. A foundational lesson, this activity assists students who may need further support in comprehending expository text. Subsequent lessons, linking the use of section headings to research activities, will be needed to allow students to apply their understanding of text features. (author/ncl)
