This means that the vocabulary, sentence structure, and overall complexity of the text are appropriate for children in those grade levels. However, it's important to note that:
* Individual reading levels can vary. A child might be reading above or below their grade level, so it's always best to assess their individual reading ability before assigning a book.
* The series includes books for different age groups. The later books in the series may have more challenging vocabulary and concepts, making them suitable for older readers.
Overall, The Diary of a Wimpy Kid series is a popular choice for young readers because it's engaging, funny, and relatable.
