This volume is the first in a series of 29 coordinated MINNEMAST units in mathematics and science for kindergarten and the primary grades. Intended for use by kindergarten teachers, this unit guide provides a summary and overview of the unit, a list of materials needed, and descriptions of six groups of activities. The purposes and procedures for each activity are discussed. Examples of questions and discussion topics are given, and in several cases ditto masters, stories for reading aloud, and other instructional materials are included in the book. The emphasis in this unit is on observing objects and phenomena with which the child is somewhat familiar. The six activity groups are entitled: (1) Exploring the classroom, (2) Exploring the school building, (3) Exploring outdoor areas, (4) I wonder, (5) Weather, and (6) Day and night. Reading lists for both students and teacher are provided as is a set of masters for a take-home booklet. (SD)
