Yes, absolutely! 8-year-olds can certainly read chapter books depending on their reading ability. Many 8-year-olds are able to read and understand longer texts, and there are countless chapter books available that are specifically written for young readers.
To find age-appropriate books, it is important to look for books with simple language and a structure that will be easy to follow. It helps to pick stories that the 8-year-old is interested in so that they stay motivated and engaged throughout the reading process.
In addition, be patient and allow your 8-year-old to read at their own pace. Encourage them to take breaks in between chapters, and provide extra activities that relate to their story if needed. By starting with shorter chapter books, your child will gain the confidence necessary to tackle more complicated texts as they continue to develop their reading skills.
