Most materials that are available every day are usually fiction materials. Here are the reasons why non-fiction books are the best for kids.
It Prepares Them For Higher Grades
The bulk of materials that children need to score high grades at school are usually on a particular subject. Non-fiction books will introduce kids to a writing style that will help them with their studies.
Expands a child’s vocabulary
Also, kids are able to improve their vocabulary with non-fiction literature books. They 
will get to learn new words that will be useful to them in academics.
Aids second language learners
If a child is being taught a second language, it would be best to use real pictures they are familiar with and normal words to aid their learning.
Teaches children more about the real world
Fiction is all about a world that does not exist and with imaginary characters or circumstances. Children need to connect with the real world and that why they also need non-fiction books. Books that are nonfiction allow kids to expand their minds beyond the things they are familiar with and understand the world we live in today
