A focus thematic unit refers to an approach that integrates learning across the curriculum around an organizing connection to give a sense of unity to the study. This involves integrating language arts with social studies, science, math and other subjects. Students develop ways to demonstrate what they have learned and make connections between different types of knowledge. The written product is the outcome rather than just part of the learning process, and it facilitates learning. Examples of connections include linking different books by the same author, books on similar topics by different authors, different animals based on their environment, and comparing different parts of the world or processes.
