Presents concrete time-teaching models to teach about making connections to fractions and measurement in which students literally measure time by using Cuisenaire rods on a form of number line to discover the meaning of the language used to describe the passing of time. (ASK)

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

Describes the history of the World's Largest Mathematics Event and how it has been used by several classroom teachers. (ASK)

Heightens the awareness of elementary school teachers, teacher educators, and teacher-education researchers of possible applications of fractal geometry with children and, subsequently, initiates discussion about the appropriateness of including this new mathematics in the elementary curriculum. Presents activities for exploring children's…

Discusses the features of a good educational game. Describes mathematics that can be developed from playing games and introduces a strategy board game called Mancala. (ASK)

Presents a sequence of activities for teaching concepts of temperature and change of temperature, and linking these concepts to graphical thinking. Offers measurement and graphing activities that use temperature as a common theme for many grade levels. (ASK)

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)

Describes how elementary school teachers demonstrated for themselves and their students how using simple drawings and visualization can improve problem-solving ability. (ASK)

Reports on rich mathematical activities that integrate different mathematics strands and learning. Describes how to introduce the task and the classroom setting, set up the task, and continue the investigation. Presents student work samples. (ASK)

Discusses possible solutions for the problem of determining how many sandwiches were made with specific ingredients that appeared in the March 1998 issue of this journal. (ASK)
