BEFORE you begin reading, it can be useful to ask questions that help you preview and make predictions about a text. This will also help give you a purpose as you read.
AS you are reading, it can be helpful to ask questions to check your comprehension and to make connections throughout a text. If there is anything that you are unsure about while reading, such as an unfamiliar word or topic, it is best to ask a question to clarify its meaning.
AFTER you have finished reading, asking questions can help ensure you understand the meaning of the text and address anything else you might want to know about the topic.
