Described is a bingo-like game for classroom drill with fractions and their equivalents. (RS)

Rules for determining the number of initial zeros and the period of a repeating decimal are stated and proved. (SD)

The author argues that the combined effects of adoption of the metric system and the popularity of hand calculators will necessitate curricular changes. Among these will be earlier and stronger emphasis on decimals as well as the introduction of new topics. (SD)

Two enrichment articles are presented; one dealing with finding partial fractions and reducing to polynomials; the other, with finding the heaviest object from eleven others of equal weight where all twelve are identical in appearance. (JG)
