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 September, October, and November; poems; word puzzles and other puzzles; mathematics activities; an exercise in following directions; art activities; science activities; language arts activities; activities to develop skills in the team sports of football and soccer; problem-solving exercises; and activities to develop self-knowledge. Several of the activities are related to the fall months or to California, Nevada, and Washington (the "states 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.
