There is a broad consensus that beginning teachers of mathematics need a strong foundation in mathematical knowledge for teaching (MKT), defined as the mathematical knowledge required to recognize, understand, and respond to the mathematical work of teaching one must engage in. One recurrent challenge in teacher education is how to provide support…

The fact that research has shown that fractions are among the most difficult mathematical concepts for elementary school students to master (Behr, Harel, Post, & Lesh, 1992; Bezuk & Cramer, 1989; Moss & Case, 1999) provides a compelling motivation for research and innovation focused on improving the available assessment and…

A unit on the division of decimals by decimals that used electronic calculators as a teaching aid is described. The learning package created, the operation of the project, and several outcomes are presented. The results strongly indicated that mathematics can be taught using a calculator. (MP)

The study looked at the initial learning of decimal concepts at grades three, four, and five. Helping children understand the concepts of decimals prior to computational use is promoted as a major goal for elementary education. The investigation is seen to have provided insights that could be applied to instruction. (Author/MP)
