This activity unit provides an example of how the construction and interpretation of graphs can be incorporated into elementary classroom activities. (MP)

An activity unit is described that helps children recognize the inside and outside of closed curves. (MP)

A seven-day unit on probability used an experimental game-oriented approach, which allowed students the opportunity to draw conclusions from experiments in which interest was high. (MP)

Worksheets utilize a paper geoboard to provide a variety of experiences with basic geometric concepts. (JP)

One student's project involved a contest of guessing how many peanuts were in a 100-pound bag. His teacher briefly reflects on the wide range of guesses and students' concept of large numbers. (MP)

Four activity sheets are given, presenting two-player games on matching, addition, and multiplication. (MP)

Ways that elementary teachers with no background in computers can begin to deal with them are detailed. High school mathematics teachers and parents who work with computers are viewed as invaluable resource people. Samples of activity cards that introduce computers to students and/or teachers are included. (Author/MP)

Projects that involve counting real things either from 1 to 100 or from 1 to 1000 are presented. The projects encourage children's guessing, ordering numbers, recording results in a variety of ways, counting elements of a subset as well as the entire set, and some problem solving. (MN)

Some problems and classroom problem-solving settings presented in a mathematics methods course for elementary teachers are described and some results of student's involvement in the program are illustrated. (MN)

Ten activity cards, designed to introduce students in upper elementary grades to programing in BASIC, are presented. The concepts and skills involved are thought to correspond to the pupils' knowledge of mathematics and aid in reinforcement. The cards represent a total of about one hour of computer time. (MP)

Describes a unit in which students design a space station. Provided are a timetable for the unit, requirements for space-station manufacturing, and an outline of the unit. Lists nine references. (YP)

Five activity lessons are proposed to present applications of probability and to exhibit its use in conjunction with statistics as a major decision-making and problem-solving tool. (MP)

Given are activities involving the use of triangles and triangle paper, in the form of problems that require searching for different possibilities to fit a given condition. (MP)

Teacher-developed materials are described, with six activity cards and a discussion of the objectives of the full set of materials. (MP)
