Enrichment activities that teach about geometry as they instruct in geometry are given for some significant topics. The facets of geometry included are tessellations, round robin tournaments, geometric theorems on triangles, and connections between geometry and complex numbers. (MNS)

Some activities involving distances and diameters in the solar system are discussed. (MP)

Six versions of the card game "Concentration" are described using cards from a teacher-made deck. (MP)

An experiment is described which started with exploratory interviews, evolved to design and administration of diagnostic tests, and led to the preparation and use of calculator-enriched teaching materials. (MP)

Outlines six activities for grades six through nine designed to illustrate the processes used by archaeologists. These processes include observation, comparison, classification, communication, use of numbers, and hypothesis formation. (AM)

Two teaching ideas that focus on baseball are presented with a poster provided for each. The first activity features baseball applications of addition, subtraction, and number concepts. The second uses a baseball setting with logic-oriented problems. (MP)

Pumpkin seeds are counted after students convert pumpkins to jack-o-lanterns. Among the activities involved, pupils learn to count by 10s, make estimates, and to construct a visual representation of 1,000. (MP)

Examines "primacy of speech perception" hypothesis. Finds covariation between reading and numeration for 94 fourth graders explained by phonetic, syntactic, and semantic cueing strategies as mediated by school-dependent basic language skills. Elasticities analysis demonstrates reading and numeration were not responsive to children's…

Alternative algorithms, "tricks," and shortcuts are viewed as ideally suited for inclusion in a systematic program of practice because of their motivational effect and the mental stimulation involved in discovering why they work. (MP)

The results of exercises related to fractions on the National Assessment of Educational Progress (NAEP) for 9- and 13-year-olds are reported. This discussion is followed by suggestions on ways to help students be more successful when adding fractions. (MP)

Insight into children's ideas about selected equality sentences is provided through a series of interviews with six- and seven-year-old pupils. The evidence indicates that children consider equality as an operator rather than a relational symbol. (MP)

The author describes the areas in the kindergarten classroom--blocks, toys, cooking, games, job charts--which can be used in furthering a child's developing mathematical skills. (KC)

Record-breaking snowfalls are the starting point of a presentation that delves into many aspects of probability and interesting and unusual aspects of viewing independent, random phenomena. (MP)

A mathematical game is described that reinforces arithmetic concepts while children practice determining equivalent representations for various denominations of money. (MP)

Specific strategies and examples for teaching mathematical computation skills are presented as samples of ways to teach starting with the concrete and ending with the abstract. (JMF)
