My students have difficulty with comprehension and sequential events when reading novels. They use an index card marked with the chapter they’re reading as their bookmark. On the card, they jot down one or two sentences about the chapter, any difficult words and the characters they met. This only takes a few minutes, because it is done when the chapter is fresh in their minds. We continue this throughout the book and keep our bookmarks together with elastic.
At the end of the book, we read the cards as a review. This is a great way to keep track of sequential happenings and write up a book summary. (I borrowed this idea from my daughter who thought of this when she was in the sixth grade.)
