Children are used to answering questions with a nod or a single word. Answering in complete sentences is fairly easy but children need to pattern themselves after someone else so that they can understand what is expected of them. Start off by asking them a question and then have your child ask you the same question.
Ex: Parent: How old are you?
Child: Five. (Typical kid answer.)
Child: How old are you?
Parent: I am 19 years old
Ask your child if they can hear a difference.
Try another question.
Parent: How was your day?
Child: How was your day?
Parent: My day was great!
Practice this method a few times.
Sometimes children may continue a thought by beginning with because. The answers are not complete. They lack a subject.
Ex. Why is your dog the best dog?
Because he can catch a ball in the air.
Sometimes children have trouble with this concept. Practice by playing ‘telephone’. If they were only to hear their half of the conversation, would they understand what the conversation was about?
Complete sentences have a who or what at the start of the sentence doing something.
