This ocean-themed unit will focus students' attention on alliteration, or repeated beginning word sounds. Students begin by reading the book Look Who Lives in the Ocean by Allen Baker, and then sharing what they notice about the words in the story. Then they work as a class to craft a definition of alliteration and record the definition on chart paper. Students continue to expand their knowledge of alliteration by finding examples in classroom books and their own writing and then adding these examples to a class list. Next, they practice revising sentences to include alliteration and then share their revisions with the class. Finally, students compose their own class book to explore the technique in their own writing. The lesson is a natural extension after alphabet books have been introduced, when writing a class book, or to supplement independent writing projects.
