Here's why:
* Vocabulary: The book uses a relatively simple vocabulary, with some more advanced words that are explained through context or are easily understandable for a younger audience.
* Sentence Structure: The sentences are generally short and straightforward, making them easy to follow for young readers.
* Themes: While the story has some deeper themes, the main plot and character development are easily accessible for children in the 4th to 6th grade range.
However, it's important to note that reading level is not a definitive measure. Some children may find it easy to read at a younger age, while others might need more time and support.
Ultimately, the best way to determine if "Charlie and the Chocolate Factory" is suitable for a child is to consider their individual reading abilities and interests.
