One of a series of activity guides designed to aid teachers in developing the thinking skills of intermediate grade students, this publication offers a variety of learning activities and resource materials. The activities and resources include: a calendar which lists important days and birthdays in December, January, and February; poems; word puzzles and other puzzles; language arts activities; activities to develop skills in the team sports of volleyball and basketball; mathematics activities; activities to develop an awareness of professional sports and athletes; and "sponge" activities for times when there are a few spare minutes in the day. Several of the activities are related to the winter months. An index lists the activities in four categories related to thinking skills from Guilford's Structure of the Intellect model: cognition, memory, convergent production, and divergent production. (DC)
