These classic pattern blocks were introduced in the early 1960s as part of the Elementary Science Study materials developed by the Educational Development Center (EDC). The six classic shapes share one common characteristic: all of the angle measurements are multiplies of 30 degrees. Shapes include the regular triangle, square, and hexagon; the…

Problem solving is one of the main components of mathematics education. This document treats problem solving as a process to be used for learning skills across the mathematics curriculum. Definition of problem solving, the environments promoting problem solving, teaching behaviors and attitudes that enhance problem solving, the criteria for good…

The logical mysteries in this book are designed to develop critical thinking and deductive reasoning skills, motivate children to read carefully, and develop memory skills. The mystery solutions are explained at the end of the book. The first nine mysteries are intended for third grade students to work on with their teacher or parents. The second…

This document is concerned with developing an understanding of problem solving by providing tasks to help students with their problem solving strategies. These tasks were used by Vermont teachers during the pilot years of the High School Mathematics Assessment and were selected by attendees of the June, 1995 Research Scoring meeting. Tasks are…

This paper is based on research work carried out in the Foundation Course in Mathematics at Goldsmiths College, University of London. The theme of the investigation was to investigate the hidden faces of cubes placed on a table. In order to do this, the following investigational teaching styles and learning strategies were adopted: investigate…

The Space Station is already capturing the imaginations of American students, encouraging them to pursue careers in the sciences. The idea of living and working in space continues to spark this renewed interest. The material in this guide was developed to provide hands-on experiences in science and math in the context of an International Space…

Mathematics has become increasingly important in this technological age. That is why it is even more important for children to learn mathematics at home as well as in school. This second edition of "Helping Your Children Learn Math" is for parents of children in kindergarten through fifth grade. It has been revised to include a variety of…

The Rivers Project at Southern Illinois University began in February, 1990 as a pilot program involving eight high schools along the Mississippi and lower Illinois River. The Rivers Project network has grown through the training of teachers from across the United States and Canada. With scientific literacy as the ultimate goal, students collect…

Describes a unit of study that promotes environmental mathematics. Automobile license plates are used for practice in classifying, examining the place value of digits, analyzing the numbers on the plates, and measurement. (AIM)

Presents facts about a super-jumbo jet and poses 11 questions on different subjects, including estimation and comparison, concerning the super-jumbo jet. Gives hints and solutions for the answers to those questions. (ASK)

Presents a quilting problem that engages students at many levels, has multiple possible solution paths, lends itself to a variety of representations, and connects many mathematical ideas. (KHR)

Describes an activity connected with mathematical definitions that illustrates the process of gradual refinement as a way to understand and construct knowledge. Presents a gradual construction of a specific geometry concept that was the result of interaction between participants in a mathematical discourse. (KHR)

Describes a low-tech, hands-on activity to improve student understanding of irrational numbers. Each student creates a number line from adding machine tapes and uses a square and a precisely folded triangle as the only measuring device. (KHR)

Investigates consumer research through an activity that helps students distinguish between qualitative and quantitative data. (KHR)
