Volume 14 Number 1 1986 January By an analytical discussion of what the slides themselves represent, students can take a topic, e.g., geometry, and find all the specific geometric shapes of natural or man-made origin in a slide, discuss the size involved, the measurement, perspective, and mathematical relationships. Language development can be encouraged by having students describe the slides. Students can physically imitate an action depicted in a slide. Recommended.
