The chart is to help them organize their answers. They ask themselves three things for each choice--1. Is it in order? (the correct choices are always in beginning, middle, end order), 2. Is it true (does it contain any details that do not happen in the story?), and 3. Are the details important (some minor details are thrown in there...the details must be supporting, important details).
I'm hoping once the kids learn some tricks to navigate these questions, they won't seem as daunting!
