A series of activities involving comparing weights of objects directly, using non-standard units, using standard units, using simple scales, and using complex scales are described. (SD)

Directions are given for activities designed to help children realize that linear measurement is continuous, that it involves the repeated use of a unit in the same way each time, and that measurement is approximate. Non-standard units as well as standard units are included. (DT)

Activities involving graphing are described. Beginning with arranging objects in linear arrays, the authors outline a sequence of activities leading up to graphing of grouped data, and circular graphs. (SD)

Planned experiences for exploration of materials are suggested for introducing geometric concepts. Examples discussed include motion, symmetry, and shape. (MP)

Attribute blocks are described, with suggestions for developing sets of attribute materials. Various activities and games are described and illustrated. (MNS)

Through a series of puzzles involving many geometric Objects,

Homemade geostrips, "angle-fixers" (cardboard circular sectors) and brass fasteners can be used by students to explore properties of angles, triangles and other polygons. Several games and other activities are suggested. (SD)

Wooden cubes can be used with task cards and teacher-made materials to develop and reinforce learning of linear measurement, area and multiplication, volume and surface area. Students can use cubes to cover area and fill boxes; later they learn to make boxes to fit specified numbers of cubes. (SD)

Activities and materials are suggested for giving practice in developing the concepts of grouping and place value. Grouping by tens leads into activities involving "money." Using the metric system, these ideas can be extended to measurement. (LS)

Directions are presented for the construction and use of line-segment strips. Examples demonstrate activities, integrate elementary geometry and arithmetic instruction. (JP)

Through a series of games, children can be given practice on making change and operating with money. (SD)
