This series of activities on spatial relationships was designed to help users acquire the skills of spatial visualization and orientation and to improve their effectiveness in applying those skills. The series contains an introduction to spatial orientation with several self-directed activities to help improve that skill. It also contains seven sets of exercises that focus primarily on spatial visualization: memory of shapes, figure completion, rotation, spatial memory and rotation, hidden shapes, and cutout forms. Each set begins with fairly simple exercises and progresses to those that are more difficult. In addition, each set builds on the skills of the previous ones. The sets of exercises are appropriate for all age levels, with the exception of prekindergarten. The activities are self-contained and can be completed with or without the supervision of an instructor. Each set of activities contains an instruction sheet that gives the objective(s) of the set, examples of everyday applications, directions for use, and suggestions for self-directed practice. Answers are given on the back of each exercise page for those who want immediate feedback and also on a separate solutions page that concludes each set of activities. Careers contingent upon the ability to perceive spatial relationships are listed and readings and games are suggested. (PN)
