The author describes a technique for teaching various aspects of the subtraction algorithm (e.g., regrouping, borrowing) by relating them to the use of money. (SD)

Topics covered include: a game involving dice, using curve stitching to teach number concepts, and an activity to introduce rectangular coordinate systems. (MP)

Instructional sequences are presented for teaching two-digit multiplication and division with one- and two-digit divisors using a base-oriented approach. (MN)

Investigated with three Down's Syndrome girls (aged 6-7 years) was the hypothesis that a videotape recording of a child correctly identifying numbers would serve to increase her number competency. (JYC)

Suggestions and examples are given for changing the passive bulletin board into an activity-oriented bulletin board which aids in teaching mathematics. (JT)

Methods that have been used with a high degree of success in correcting errors in subtraction are discussed. (JT)

An approach is illustrated that introduces selected models of addition and subtraction to students who have previously learned a model for either operation. (JT)

Described is a multiplication unit for intermediate aged emotionally disturbed boys which used citizen band radio terms and a drawing of a road to record individual progress. (CL)

An activity project is described which encourages students to question and experiment. Appendices provide examples of student results. (MNS)

Two teaching studies were conducted, based on a descriptive framework and diagnostic interviews described previously. In the pilot study, low-achieving students were taught individually; in the main study, they were taught in a group. Performance improved in both cases. (MNS)

The importance of encouraging students to think about their actions in playing educational games is noted. A game is presented with mathematical topics that could be explored and variations on the game described. (MNS)

Using sweeps to find areas, applications of reflections to miniature golf, and zeroing in on zeroes are each considered in the brief articles in this department. (MNS)

This report on mathematics education in Soviet elementary schools was prepared by a writer for the Novosti Press Agency in Moscow. It notes that mathematics is taught by subject specialists beginning in grade 4 and provides details on both curriculum and instructional practices. (MNS)

In our investigation of preservice secondary teachers' understanding of irrational numbers we focus on how different representations influence participants' responses with respect to irrationality. As a theoretical perspective we use the distinction between transparent and opaque representations, that is, representations that "show"…

Teachers and teacher educators interested in synthesizing their current practice with new mathematics standards will welcome this highly useful volume. The QUASAR Project at the University of Pittsburgh presents prevalent cases of mathematics instruction drawn from their research of nearly 500 classroom lessons. The Mathematical Tasks…
