[Strategy] Interest Centers or Interest Groups [Definition] Interest centers (usually used with younger students) and interest groups (usually used with older students) are set up so that learning experiences are directed toward a specific learner interest. Allowing students to choose a topic can be motivating to them. [Example] Interest Centers: Centers can focus on specific reading skills, such as phonics or vocabulary, and provide examples and activities that center on a theme of interest, such as outer space or students' favorite cartoon characters. Interest Groups: For a book report, students can work in interest groups with other students who want to read the same book. [Focus of Differentiation]
