The goal of selecting appropriate reading materials for students involves ensuring that they are engaged and able to comprehend the text. Choosing books where students have five or fewer known words can significantly limit their ability to grasp the overall meaning of a text. It is essential for students to encounter a certain level of familiarity with vocabulary; otherwise, the reading experience can quickly become frustrating and detrimental to their learning process.

Focusing on books where students are familiar with the subject matter enhances their ability to connect new information with existing knowledge, facilitating better understanding. Materials that challenge students without overwhelming them are equally important, as they can encourage growth and development in their reading skills. Additionally, selecting texts that align with students' interests fosters motivation and engagement, making the reading process more enjoyable and effective.

A balanced approach that considers vocabulary familiarity, background knowledge, appropriate challenge levels, and student interest would more effectively support students' reading development.
