In this online tool, students can learn about and write diamante poems, which are diamond-shaped poems that use nouns, adjectives, and gerunds to describe either one central topic or two opposing topics (for example, night/day or winter/spring). Examples of both kinds of diamante poems can be viewed online or printed out. Because diamante poems follow a specific format that uses nouns on the first and last lines, adjectives on the second and fourth lines, and gerunds in the third and fifth lines, this tool has numerous word-study applications. The tool provides definitions of the different parts of speech students use in composing the poems, reinforcing the connection between word study and writing. It also includes prompts to write and revise poems, thus reinforcing elements of the writing process. Students can print their finished diamante poems.
