Advocated is developing intuitive ideas of limits whenever the opportunity arises in elementary mathematics. Examples are given for geometry, fractions, sequences and series, areas, probability, graphing, and the golden section. (MNS)

Introduces an approach to teaching about the skin that involves making, comparing, and classifying its prints. Outlines the procedures for making skin prints and explains why different kinds of patterns exist in various parts of the body and also among individuals. (ML)

Curiosities offer an interesting alternative to traditional methods of attacking problems. An illustrative situation is given, with graphical, computer, and analytical methods used to solve the problem. (MNS)

Ideas for teaching the concepts of percentage, recognition of patterns in percentages, percentage as a special ratio, ways of finding percentages, and fractional percentages are presented. (MNS)

The focus is on the problem-solving strategy of find a pattern, with a problem explored to illustrate how to use the strategy. Other tips concern classroom climate, checking skills, research, and type of problems. (MNS)

Stresses that powers are all based on geometric progressions which start at unity. Various patterns are discussed. (MNS)

Activities involving estimation of the number of objects in a configuration can motivate students to consider parametric models. (SD)

The results provide evidence of remarkable consistency in both accuracy and manner of performance from first grade through college age levels. (Authors)

The problem of determining the number of squares on a checkerboard is extended to finding the number of rectangles on an n x n board and finding the total numbers of cubes and rectangular solids in an n x n x n cube. (DT)

Children from 4 to 7 years of age were tested in a structured perceptual task in which haptic manipulation was available, but not required. The extent of haptic involvement with the stimulus material and its effect on performance in a perceptual recognition task was then determined. (Author/CB)

The similarity match took longer than the identity match, and the difference in latency increased as the number of lines in the pattern increased. (Author)

Results demonstrate that 12 - 15 - week-old male infants smile to nonsocial stimuli, and offers support for the recognition hypothesis of infant smiling. (Authors/MB)

Outline faces were presented for rating along six dichotomous attributes with features varying systematically. Differences were found to be largely attentional, with certain features invariably being differentially employed and associated with certain attributes across all samples. (WY)
