Early childhood is a time of discovery when learning occurs at every turn. The task that early childhood teachers face is how to teach a class full of students who fall at each end of the learning spectrum (and every place in between). This article describes an easy and effective way to address widely diverse needs among young learners--to empower…

Leaders in professional development have called for more learner-centered professional development opportunities for teachers. These approaches allow teachers to have some choice about the content and pedagogies on which they focus during professional development courses. This paper shares case studies of three participants from InterMath, a …

Charlotte, the author's 11-year-old daughter, was born with Down syndrome, and is currently attending the local middle school. In terms of her disability Charlotte is developing very well and has a reading age of 9+, however her maths skills age is approximately 4 years. It is not necessarily the case that if a child has good language and literacy…

In this article, the author presents a new maths aid for teaching place value, addition and subtraction up to 1 million. The need for a resource to help his wife understand place value motivated the author to create "Counting Cards". Here, he shares his invention, in the hope that it will help others. (Contains 4 figures.)

Games are among the many types of activities that can be used to help promote number sense. Chosen and used wisely, games encourage learning and motivate many students to grasp concepts more quickly and fully. This article describes a popular and easy-to-implement number sense game--called Digits and Dice--most commonly used in conjunction with…

In this issue's "Classroom Notes" section, the following papers are discussed: (1) "Constructing a line segment whose length is equal to the measure of a given angle" (W. Jacob and T. J. Osler); (2) "Generating functions for the powers of Fibonacci sequences" (D. Terrana and H. Chen); (3) "Evaluation of mean and variance integrals without…

This article describes a lesson study project that explored the impact of using storybooks to teach mathematics in three kindergarten classrooms. The study involved three kindergarten teachers and three university educators, who collaborated to plan, design, implement revise, and reflect on a unit of mathematics that focused on the concept of…

Seriation refers to the process of ordering objects along single or multiple magnitude dimensions such as length, weight, and color. The ability to order objects in terms of some attribute is essential for the child's understanding of the properties of numbers. This study investigated the effect on seriation performance of increasing both the…

Many have argued for the importance of numeracy, yet little is known about the opportunities for numeracy available to people in their daily lives. In this study, characteristics of rational numbers in magazines written for children, teenagers, and adults were analyzed and compared. Analysis indicated that difficult mathematical concepts that…

The Colorado Model Content Standards for Mathematics were designed to serve as a guide for school districts as they define standards that will enable every Colorado student to develop the mathematical literacy needed for citizenship and employment in the 21st century. A new vision is provided of the content students should study in order to…

Thirty-six studies on individualizing instruction in arithmetic are reviewed, and the general findings emerging from the combined research are discussed. (SD)

Using arrays of dots and grids many numerical concepts can be illustrated for students. (SD)

A game involving operations on whole numbers, observing patterns in the relationships between operands and results, and seeking problems yielding various numerical solutions is described. (SD)

Many concepts can be introduced informally through activities. Among those which can be investigated using easily-made 10-by-10 pegboards are geometric shapes, coordinate systems, grouping and regrouping, and addition of two-place numbers. (SD)

Fourth-grade students and their parents attended evening mathematics classes together. Parents and students helped each other in solving arithmetic problems. Scores of students on a posttest were significantly better than on a parallel pretest. (SD)
