Celebrations is a look at over 300 international holidays and celebrations arranged by month. The book, which has an attractive 8 1/2 by 11 format, begins with an introduction aimed at classroom teachers. Though relatively brief, the intro does an excellent job of encouraging teachers to integrate the celebrations across the curriculum. The study of a particular holiday does not have to take place on the holiday itself, for instance, but can be incorporated into geography, language arts, science, environmental studies and even music classes. The introduction also deals with the thorny issue of how to handle religious holidays.
