Reading with purpose 
Active reading encourages understanding through engagements with the text. If your child is interested in the material, they will be far more likely to involve themselves in learning about it and become a more active reader.

Learning vocabulary 
Learning new vocabulary will help your child get a deeper understanding of what they are reading. Ask your child to write down any new words that they don't understand and look up the meanings with them. Depending on the age and ability of the child, teach the new word and explain the meaning to them. 

Talking about what they read.
Discuss the story by asking literal questions or expand their thinking by having them make  inferences. For example, why do you think the girl hid the toys from her friends.?
