Read with your child for 15 minutes every night. Ask questions about the story to check their understanding. They should be able to describe where and when the story takes place. Who were the characters in the story? What were the events that happened in the story? What was the problem in the story and how was it solved? Was it real or fantasy? These questions will help train your child to think about what is happening in any story that they read, which will help to increase their comprehension. Rereading familiar stories also helps with comprehension, as well as with fluency. Check with your child's teacher to find out how many words they should be able to read per minute, and then time them once a week for practice to see if they are improving.
