Young children gain emergent literacy skills during the preschool years. Oral language development is enhanced as students engage in dialogue with teachers and peers. The use of topical vocabulary is linked to greater gains in students' vocabulary development. Students acquire emergent writing skills as they participate in spontaneous and guided writing activities. Teachers play an essential role in promoting literacy development through intentionally designing literacy-rich environments and learning experiences. Literacy-related play can be enhanced when teachers guide students' use of content-specific props. The Entomologist Tool Kit is an example of a prop that jump-started preschoolers' vocabulary, oral language, and emergent writing development in a preschool classroom. This article gives steps for replicating this prop.
