Reading comprehension involves understanding text, connecting it to prior knowledge, critical evaluation, and monitoring understanding. There are different reading strategies like skimming, scanning, extensive, and intensive reading. Before reading, teachers can pre-teach vocabulary, have students predict from titles, sequence pictures, and use pictures. While reading, students can tell the story, make predictions, focus on words, and use pictures. After reading, activities include rearranging sentences, cartoon strips, drawing pictures, rearranging words, acting out stories, wall stories, writing new endings, and altering versions.
