Discusses an algorithm that converts a fraction in simplest form into a terminating decimal and allows students to explore the efficacy and conceptual bases of a mathematical algorithm. (ASK)

Describes two card games to motivate students to understand number sense concepts that can be used at the 2nd-5th grade levels. (ASK)

This book guides teachers in the appropriate use of calculators in math classrooms in grades 3-8. This resource is organized into two parts. Part One addresses the broad range of classroom teachers' questions and concerns about using calculators for teaching mathematics. Issues covered include: (1) How can calculators support helping children…

The World's Largest Math Event (WLME) 4 is the National Council of Teachers of Mathematics' (NCTM) celebration of mathematics and mathematics education and is the highlight of Mathematics Education Month. This year's event is slated for April 30, 1998 with the theme "Landmarks: Seeing the World by Numbers". This theme encourages students…

Discusses the role of conjectures in learning mathematics, how conjectures demonstrate mathematical power, and how conjectures build understanding and encourage connections. (ASK)

Provides an overview of the conceptual analysis of the unit fraction that provided the framework for developing a comprehensive array of fraction activities for fourth-grade students. Reveals the students' difficulties in learning the unit-fraction concept and discusses the didactical implications of these difficulties. Contains 15 references.…

Presents a problem introducing pupils to the ideas of consecutive and integer while practicing addition. Investigates the overall pattern of results with regard to formulating some general results, considers the algebra of the problem, and suggests proofs of why some numbers can and others cannot be formulated in this way. (ASK)

Suggests scales as alternative representations of numerical concepts and operations that can be used as arithmetic-mean machines, adding machines, multiplication machines, and geometric-mean machines. (ASK)

Presents solutions for a problem concerning doubling a recipe from a previous article on number concepts in the October 1997 issue. (ASK)

Numbers can be represented in a variety of ways--through pictures, diagrams, symbols. Each representation highlights different features of the number and the number system. This study aims to explore pupil understanding of number both within and across representations. A computer environment (suite of programmes) was created within which…

The objective of preschool teachers should be to determine the mathematical ability of preschool children and improve their skills using meaningful teaching methods through pictorial demonstration and manipulative models. Children who receive number concept instruction through hands-on play models, activities, and discussion show greater…

Presents activities that focus on number sense. (KHR)

Presents an historical lesson on the development of numbers and the special characteristics of zero. Includes activity sheets designed to help students focus their attention on the value of numerals including zero, place value, and operation with zero. (KHR)

Explains how number work in elementary school can be extended to prepare students for algebra. Suggests some practical strategies that focus on five aspects of number knowledge essential for algebra learning. (ASK)

Features a question that focuses on the use of cryptology to teach modes. (ASK)
