In first-grade literacy, which of the following is not emphasized compared to Kindergarten?

In first-grade literacy, identifying key details in texts becomes increasingly important as students start to build on their foundational skills from Kindergarten. In contrast, first graders focus more on higher-order comprehension skills such as determining the central message and analyzing different text types, which were introduced in Kindergarten but are not the primary focus at that stage.

The emphasis shifts towards understanding more complex ideas and themes rather than just identifying details. Although distinguishing storybooks from informational texts and understanding sensory language are significant components, first graders are expected to refine their understanding of these concepts, but identifying key details continues to be a skill developed from Kindergarten rather than something that is not emphasized. Therefore, identifying key details in texts is not a primary distinction between Kindergarten and first grade, making it the correct answer in this context.
