Surveys the many categories of people comprising the homeless population and describes the methods that have been used to estimate their numbers. Concludes that the vast effort required to enumerate homeless people would be better directed toward focused research on the needs of identifiable subgroups. (DM)

A way that allows students to discover a strategy for determining the area of rectangles, squares, parallelograms, triangles, and trapezoids is described. Students use grid paper and scissors to determine the number of square units that cover a specified space. (KR)

Preschoolers' performance on two tasks demonstrated that, given a perceptually available set of dolls, they were able to use number words to determine the quantity of a hidden or nonexistent set of items that was in a known ratio to the available set. (MM)

Presents a problem on counting squares that emphasizes the computation and identification of squares. (ASK)

Presents mathematics questions to analyze what advertisements are saying mathematically. (ASK)

Presents two different research tests for teachers to conduct in their classrooms to gain insight into their students' number sense. Provides test results from Taiwan for comparison. (ASK)

This study investigated whether specific academic deficits were associated with attention-deficit disorder subtypes (with or without hyperactivity) with 40 elementary students. Results support the hypothesis that inattention exerts a specific and deleterious effect on the acquisition of arithmetic-computation skills. Implications for ADHD…

Evaluated different types of statistical assignments in a research methods course for graduate students in public affairs administration. Found student learning could be improved through appropriate readings, hand calculation, and the use of computers. Hand calculation was particularly effective in improving student confidence in using statistical…

Examines 109 children from grades 3 through 6 for computational facility and the relationship between automaticity, or efficient processing of addition facts, and success in more complex tasks. Indicates that most errors on the multidigit sums were due to fact inaccuracy, not algorithmic errors. Discusses instructional implications for students…

Examines the computational strategies of 10 young street vendors in Beirut by describing, comparing, and analyzing computational strategies used in solving three types of problems: (1) transactions in the workplace; (2) word problems; and (3) computation exercises in a school-like setting. Indicates that vendors' use of semantically-based mental…

Assessed the strategic flexibility of students in mental arithmetic up to the number 100. Results from 60 Dutch second graders show that students' preference for certain mathematical procedures depend on the number characteristics of the problems, indicating that the students had a good conceptual understanding of numbers and procedures. Actual…

Compares the approaches to teaching division in Britain and in Holland where different emphasis is placed on the development of mental and written methods. Describes how it is common for pupils in Britain to work from an early stage with pencil and paper rather than mentally whereas early emphasis is placed on mental strategies in Holland. (ASK)

Explores the mathematical problem posing and problem solving of U.S. (N=181) and Chinese (N=223) sixth-grade students. Reports that while Chinese students outperform U.S. students on computational tasks, there are many similarities and differences between U.S. and Chinese students in performing relatively novel tasks. Discusses the direct link…

Presents a game in which students are told to say 'Fizz' on multiples of two and 'Buzz' on multiples of three while the teacher proceeds to count upward by one. (ASK)

Presents an activity for identifying patterns in the book "The Grouchy Ladybug" by Eric Carle. The book is appropriate for teaching many concepts including time, developing an alternative story line, and constructing a new book to involve children in thinking about how time passes on a clock as part of exploring patterns.
