If your child is reading alone, you can check their reading skills by reading a chapter yourself and then asking questions about that chapter. Once the book has been read, ask your child what the author's purpose for writing the book. The author could be writing to give information, entertain, persuade, or to give instructions. Ask your child to compare characters in the book. How are they alike and different.
Every story has a problem and a solution.
Have your child identify the problem and solution in their book. Ask your child to tell you the story briefly. Their summary should include the problem, solution and the events pertinent to the plot. Help your child pinpoint the time and place the story happened. Talk about the feelings the characters are experiencing in the story.
