Because most computer comprehension programs simply have multiple-choice questions to test basic recall, your daughter is going to need more help this summer to improve her comprehension skills. For children to truly understand what they have read, they need to have more advanced comprehension skills that include making inferences, relating details to major ideas, and knowing the sequence of events.
One of the simplest ways to improve your daughter's reading comprehension is simply to have her retell what she has read to you. Begin with very short passages. If she hesitates, ask questions like: What happened next? Where did the story take place? Who else is in the story? Besides working with your daughter, you may also want to have a tutor help her.
