The author argues that with the adoption of the metric system of measurement, common fractions became inappropriate to the school mathematics curriculum. (SD)

Ancient numeration systems form the basis for these worksheets. (SD)

Development of the repeating decimal expansion for rational numbers is discussed. Expressions for numbers in other bases are also presented. (SD)

Building mathematical sentences is the focus, with worksheets for practice with basic facts and fractions in a problem-solving setting, using logical reasoning. (MNS)

This brief report focuses on the cognitive level of decimal problems in 16 textbooks. Activities at the application level are included, but seldom are higher-order intellectual behaviors found in the books. (MNS)

Four worksheets are provided for developing decimal concepts. For levels 1-2, dollars and cents is the focus; for levels 4-5, tenths and hundredths; for levels 5-7, comparing and ordering decimals; and for levels 6-8, estimating with decimals. Teaching suggestions are included. (MNS)

Provides a short list of integral triples for the design of problems employing unit fractions (so solutions will be positive integers). Also presents an algorithm whereby both primary and imprimitive sets of triples can be easily obtained and shows how to extend the algorithm to solve three-variate unit fraction equations. (JN)

The game of Fractional Dominoes is illustrated. (DT)

This book is designed to help adults gain the range of math skills they need to succeed in life and work and on standardized tests including the GED. It is expected to help students overcome math anxiety, discover math as interesting and purposeful, and develop good number sense. Lessons are organized around four strands: (1) skill lessons…

In a teaching experiment, I examined a theoretical model of mathematics teaching and learning in practice. In this paper I focus on how the model can guide the teacher's thinking about students' understandings and the generation of activities that foster intended transformations in those understandings. As a research-teacher I taught, twice a week…

Two classroom games are discussed, one focusing on the relationships between decimals, percents, and fractions and the other on spatial perception, identification and discrimination of geometric figures. Materials needed, construction suggestions, and rules for playing the games are given. (LS)
