Ms. Smarty Pants : Main Idea This is a great, to-the-point anchor chart Can redo for nonfiction. Look at the title and photographs and headings. Use text instead of story. There's not really a main idea in a story.
Making predictions in a story is such an important element of imagination and comprehension for a student. I have seen this in my internship where students will give ideas in a large group reading what they will believe will happen in the story. I have also implemented more predictions in literacy by doing a picture walk with the students.
