I found this very comprehensive list of questions that would support this activity and keep the conversation interesting and dynamic. This is not my document, but I do find it very useful.
This activity should only take about 15 minutes a night, but the benefits can last a lifetime. Talking about what they read is one of the best ways for children to not only demonstrate comprehension but it's also a great way to develop critical thinking skills.
As always, we continue to talk about what fluent readers do, and by reading to an adult each night as described above, students would also be able to practice these skills pictured below.
