One of a series of activity guides designed to aid teachers in developing the thinking skills of primary 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; poems; facts and an activity about Hanukkah; a flannelboard story; word puzzles and other puzzles; science activities; arts and crafts activities; mathematics activities; and body movement exercises. Many of the activities are related to Christmas or to Texas (the "state of the month"). An index lists the activities in five categories related to thinking skills from Guilford's Structure of the Intellect model: cognition, memory, convergent production, divergent production, and evaluation.
