Presents an activity in which students use geometric figures, rep-tiles, to design a tile floor. Rep-tiles are geometric figures of which copies can fit together to form a larger similar figure. Includes reproducible student worksheet. (MKR)

Four worksheets are presented, each using cubes to develop students' spatial visualization abilities. Directions and answer keys are both included. (MNS)

Dissection work with two-dimensional shapes is discussed, and patterns to be copied are given on three worksheets. A fourth worksheet contains instructions for pupils to make their own shapes and dissect them. (MNS)

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…

The properties of the cube are explored. A set of activities is given that forms the basis of a class project on discovery. (MNS)

Presents activities using interpretation of visual clues and making decisions on the basis of those clues. Students in grades 2-4 use pictures of Native American tribal clothing.

Some activities with tangrams and their use for investigating fractions, constructions, and percentages are presented, with worksheets included. (MNS)

To help students develop measurement skills using metric units, an activity on making a box is described, with a worksheet for students. A second article discusses graphing elementary functions with a real domain, while a third article describes computer-assisted practice in graphing sine and cosine functions. (MNS)

Sample materials from a primary training packet are included. The packets were developed as a part of a teacher development program aimed at improving elementary mathematics by giving teachers practical ideas. The sample student materials are drawn from the areas of geometry and oral mathematics. (PK)

Zoo Zillions contains five activities for grades K-2: Annie's Jungle Trail, 3D Gallery, Number Line Express, Gnu Ewe Boutique, and Fish Stories.
