If she's having trouble retelling her story, try stopping at shorter intervals rather than waiting till the end of the story to summarize what she's read. Your modeling how to do this will really help. Children often remember more if they fill in something called a graphic organizer. This is basically an outline of the story, with a place for characters' names and characteristics, the setting, the problem in the story, important events, and how the problem is solved. Just about every story follows this format. Once it's filled in, it will be much easier to capture what's important in the story for her retelling. And certainly have a talk with your daughter's teacher to see if these comprehension difficulties are major issues in class. Ask if she would recommend that your child receive extra help outside school. Good luck!
