Describes how to deal with students' structuring of rectangular arrays of squares and other two-dimensional regions. Presents activities that connect spatial structuring to the development of multiplicative thinking. (ASK)

Presents mathematics activities on tangrams to study geometrical shapes such as polygons, symmetrical shapes, and tangram jigsaws. (ASK)

Introduces a project in which students use dynamic geometry software with a TI-92 graphing calculator to study geometric constructions. Concludes that interactive technology can enhance the geometry curriculum and better meet the needs of visual and tactile learners than the traditional approach. (ASK)

Describes a lesson in which second grade students learn about data management, number sense, and patterns as they analyze, classify, and describe their fathers' shoes. (ASK)

As the class is learning new names and new faces at the beginning of the school year, it's the perfect time to have fun with names and learn some math concepts at the same time. This document describes examples of different number games that can be played with students.

Teachers can help students build a disposition to use connections in solving mathematical problems, rather than mathematics as a set of disconnected, isolated concepts and skills. One activity that addresses the criteria that involve problem solving, reasoning, communication, and representation that together create a vision that encourages…

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 purpose of this article is to describe findings from a study of teachers' social interaction during discussions about students' thinking. The goal of the discussions was for the teachers to interpret their students' thinking as revealed from work on non-routine, thought-revealing mathematical tasks, known as "model-eliciting…

This observational study examines the classroom dynamics occurring in a collaborative math lab activity in a third-grade classroom. Specific classroom interactions are identified as resources for cultivating children's interest and understanding of mathematical knowledge. Dialogic interchange and physical positioning of teacher and students is…

This article describes a problem-centered curriculum for grades 9-12, using problem sets developed by a mathematics department and designed to take the place of textbooks. The students discover mathematical concepts in the context of the problems and activities in the materials.

This study focuses on the constructions in terms of area and perimeter in equivalent triangles developed by students aged 12-15 years-old, using the tools provided by Cabri-Geometry II [Labore (1990). "Cabri-Geometry (software)," Universite de Grenoble]. Twenty-five students participated in a learning experiment where they were asked to construct:…

The purpose of this study was to discover and successfully implement multiple strategies for differentiation that would engage and motivate Talented and Gifted (TAG) learners. Six TAG students from a third grade general education classroom setting participated in this study. Differentiation strategies of a learning style inventory, a project…

In this article, the author describes the Space Camp at the U.S. Space & Rocket Center in Huntsville, Alabama, where deaf and hard of hearing students can pilot spaceships, conduct experiments, and dodge meteorites. Each year in the spring, students from schools all over the United States attend a one-week, hands-on learning experience in…

This article describes a lesson unit in which students constructed tables and graphs to represent the growth of different trees. Students then compared the graphs to develop an understanding of slope.

This book is designed to present mathematical problems and tasks that focus on the National Council of Teachers of Mathematics (NCTM) curriculum and evaluation standards in the context of aerospace activities. It aims at actively engaging students in NCTM's four process standards: (1) problem solving; (2) mathematical reasoning; (3) communicating…
