Describes a professional development project to increase teachers' understanding of proportional reasoning, the thinking patterns associated with proportional reasoning, and the applications of proportional reasoning across the middle-grades curriculum. (YDS)

Described is the Delaware Elementary Mathematics League; a state mathematics competition for grades 4-6. Included are specific sample test items and a discussion of how they can nurture the development of problem-solving skills. Sample tests are also discussed. (CW)

Described is a study in which three instructional approaches were applied in second grade classes. Discussed are proportional materials, nonproportional materials, nonproportional materials with pictorial models. Findings, results, and recommendations are presented. (CW)

One teacher's approach to the development of number sense while using calculators is outlined. The relationship between number sense and calculation is discussed. Teaching strategies and two worksheets used in this approach are presented. (CW)

Presented are three physics problems from the New Zealand Entrance Scholarship examinations which are generally attempted by more able students. Problem situations, illustrations, and solutions are detailed. (CW)

Presented are ideas for the utilization of Microsoft Works in the secondary mathematics classroom. The spreadsheet and graphing capabilities of this software package are demonstrated for several topics including the concept of slope for first year algebra, and creating and interpreting graphs for a general mathematics class. (Author/CW)

Explores developmental (age) differences in meaning that children at four grade levels assign to count and relational quantifiers. Results indicated 92 percent of the children demonstrated understanding of all count quantifiers. For relational quantifiers, mean numerical values assigned to four terms followed expected patterns; understanding of…

Reports examples of the behaviors, including kinetic and vocal, used to facilitate problem-solving based on observations of four seventh-grade students. Discusses the use of the behaviors in problem-solving teaching. (YP)

Describes four activities designed to discover numerical patterns using a calculator or paper and pencil. Provides tables and figures for the activities. (YP)

Investigates children's behaviors and conceptual achievements in the transition from informal calculation strategies to a written division algorithm. Describes five different strategies observed in the solution of division problems. Discusses the implications of the children's behavior. (YP)

Presents two practice-discovery activities to furnish computational review in a nonroutine setting. Provides a worksheet for the activities. (YP)

This study, involving 40 students (grades 2-8) with learning disabilities, found that students who participated in curriculum-based measurement test-taking strategy training scored higher on a posttreatment computation test than students without the strategy training. Use of a goal strategy did not result in any achievement differences.…

To answer students' questions about predicting grade averages or projecting grades needed to attain specific grade goals, academic advisors can use computerized grade calculations. Spreadsheet and HyperCard versions of grade calculation software are discussed and illustrated, and suggestions are offered for using them in specific advising…

Describes "Kid Cuts," an arts and crafts computer software program for students in prekindergarten through sixth grade that provides 22 activities in 6 curriculum areas. An example is given of an activity for kindergarten and first graders related to counting that includes library media skills objectives and mathematics objectives. (LRW)

Three experiments explored the developmental relationship between counting and number conservation in children from three to six years old. Results indicated that there was a close relationship between the two; that only the oldest children gave evidence of conserving; and that, in general, there is evidence of protracted development in young…
