Presents a mathematics investigation in which students discover number patterns in physical structures and express their generalizations algebraically. (MKR)

Analysis of the role that (n=4) second graders' use of the hundred board played in supporting their conceptual development found that the board did not support the construction of increasingly sophisticated concepts of 10, but did support their ability to reflect on their mathematical activity. (54 references) (Author/MKR)

Included are activities and guidelines which suggest ways to use large numbers in relative terms so that they can become more meaningful for elementary mathematics students. Several spreadsheet projects illustrate the incorporation of the recommendations from the NCTM Standards dealing with number sense. (JJK)

Describes a number line created by fourth-grade students containing paper rectangles to represent the basic multiplication facts. The use of this number line can help students to understand factoring, prime and composite numbers, and beginning fraction concepts. (MKR)

Quantitative literacy for students with deafness is addressed, noting work by the National Council of Teachers of Mathematics to establish curriculum standards for grades K-12. The standards stress problem solving, communication, reasoning, making mathematical connections, and the need for educators of the deaf to pursue mathematics literacy with…

Observes several regular error patterns when a group of seven-year-old Italian children transcode arabic numerals to verbal numerals. Explains the development of transcoding ability by an asemantic model using production rules. Contains 15 references. (Author/ASK)

Presents educational games to promote mathematical reasoning and problem solving in the primary grades. Children take charge of their learning and create exciting challenges for one another. (ASK)

Presents evidence from data on how well five first-grade classes did without any formal instruction showing that if children's numerical reasoning is strong, then formal instruction of missing addends is unnecessary. Explains the findings in light of Piaget's constructivism and discusses educational implications. (ASK)

Describes the use of a variety of strategies to teach estimation and other mathematics concepts in an inclusive urban fifth-grade classroom. The collaborative program (involving the teacher, the mathematics consultant, and the special-education consultant) utilized cooperative learning, estimation techniques, calculators, graphic organizers, links…

Proposes and analyzes game design as a learning environment for students and teachers to build upon and challenge their existing understandings of mathematics,to engage in relevant and meaningful learning contexts, and to develop connections among mathematical ideas and real-world contexts. Contains 55 references. (Author/ASK)

Presents student responses to a problem appearing in the February, 1999 issue about mathematical patterns and number concepts. (ASK)

Presents a problem for grades 3-6 on number concepts and computation. Also provides guidelines for teachers to improve problem-solving practices in their classrooms. (ASK)

Two experiments investigated infants' sensitivity to amount of continuous quantity and to changes in amount of continuous quantity. Found that 6-month-olds looked significantly longer at a novel quantity than at the familiar quantity. Nine-month-olds looked significantly longer at an impossible event than at a possible event. Findings question…

Examines the differences in preservice elementary school teachers' perceptions between divisibility by two, or evenness, and divisibility by another number. Concludes that the equivalence of the number properties of being even and being divisible by two is not taken for granted; rather, the parity is often perceived as a function of the last digit…

Compares sixth-grade American students to three samples of (Chinese, Japanese, and Taiwanese) sixth-grade Asian students to determine if the well-documented mathematical achievement of students from these Asian nations might be due in part to a greater understanding of mathematical representations. Indicates that all Asian samples scored…
