Games and activities, which are fun, practical, and related to the child's world, are presented. Suggestions are given for building skills in estimating lengths, guessing how many, recognizing patterns in counting, multiplying with "waffles," classifying by attributes, and adding and subtracting with special cards, relays, and play…

A set of geometric pieces is used to solve problems involving geometry, combinations, division, and money. (JT)

The game of "Life" can be easily adapted for play by small groups and can be used in classroom activities. (SD)

Multibase arithmetic blocks are used to investigate the minimum number of blocks of each size to make a square of a given size in a given base. Generalizations are made to any size and any base through pattern recognition. The problem is extended to rectangles, cubes, and rectangular solids. (LS)

Activities in which students make models of a variety of geometric solids are described. (SD)

Many concepts can be introduced informally through activities. Among those which can be investigated using easily-made 10-by-10 pegboards are geometric shapes, coordinate systems, grouping and regrouping, and addition of two-place numbers. (SD)

The number concepts of greatest common divisor and least common multiple are related to star patterns created through line designs. (JT)

Track cards are manipulative materials used to promote verbalization, spatial perception, eye-hand coordination, simple problem solving, and fun in doing mathematics. (JT)

Primary students can use a geoboard to develop perceptual motor skills, pattern observation, and thinking ability by reproducing designs and developing strategies for games. (SD)

Eight teaching ideas involving circular shapes and patterns are described for grades one through eight. (JT)
