Skills in sorting objects into sets, matching elements of one set with those of another, and forming subsets from larger collections are extended to show their application to everyday life.

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)

Activities are presented that permit students to gain firsthand experiences with ideas about two-dimensional and three-dimensional shapes and volume that textbook exercises rarely provide. (MP)

Paper folding and coloring activities are presented which involve the use of rectangular and square regions as models for basic fraction concepts. Rules for a fraction game also are included. (DT)

A series of activities is suggested for helping children deal with the continuity and order of events in time, with measuring time, and with reading the clock. (DT)

Variations on familiar games which can be used to motivate mathematics learning are described. (SD)

Several activities in which students use geometric shapes and their shadows to study geometric concepts are described. (SD)

Activities are described which make use of rectangular arrays as a means of illustrating multiplication facts and the distributive property. (DT)

Through a series of puzzles involving many geometric Objects,

The authors describe several board games which can be made by the teacher and used to develop mathematical concepts (e.g. one-to-one correspondence) or reinforce basic skills. (SD)

Diverse activities using large blocks are described. By building and comparing configurations children can be led from concepts like long and high to concept of ratio. Games and activities to help build other concepts are also described. (SD)

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)
