Making inferences with your child is one reading strategy that carries into all subject areas and other areas of life in general. It is very powerful and yet easy to find opportunities to do it throughout your day. With regards to reading, making an inference is also known as reading between the lines. 
The reader must put together the information the author provides and the information that the reader already knows to come up with an observation or conclusion about the text. You can have fun with it and look at it like you are a detective looking for clues in order to make an inference. My favorite way to look at inferring is: Inferring is seeing what isn’t being said.
For instance, you may smell garlic in the air and infer “Hmmmm we may be having something Italian for dinner!”
You may read about a character who is an only child who lives in a rural setting and infer that he/she is lonely at times.
You may see the look on a character’s face and infer that he/she is not happy, even if it doesn’t state it in the writing.
What ways have you done some inferring with your child recently?
