Holidays are enjoyed by most everyone, but few clearly understand the meanings, traditions, and values behind these special days. Holidays tell us much about the past, and also about the values that those in the present find worth preserving for the future. Using holidays to teach in a variety of subject areas across the K-12 curriculum can be an enriching and interesting way to communicate content standards and values. This course examines over 30 holidays observed in America, explains their history, and stimulates thoughtful analysis about the values these days of celebration and remembrance promote. Through a concise and helpful historical resource book authored by the instructor and by means of a variety of learning activities, students will gain a new appreciation for holidays and their potential as a significant interdisciplinary teaching tool.
