Presents a unit of study involving tangrams that integrates geometric relationships, scale drawings, graphing, patterns, and logical thinking. Provides worksheets for independent and cooperative activities to discover geometric shapes using a specified number of tangram pieces. (MDH)

Describes an eight-day graphing unit for grades four through six using data collected from a local cemetery. Provides the activities of each day and excerpts of discussions taking place during the lessons. Concludes that working with real data helps students construct meaningful graphs. (MDH)

The language-experience approach to problem solving is discussed. A theme park unit provides illustrations of how problem solving can be developed. (MNS)

A description of a unit on banking for primary grade students includes the set-up and use of a classroom banking procedure. (DT)

Presents a 6-day unit for grades 2-4 to enable students to understand the concept of time and how the analog clock works. Using concrete materials and cooperative learning, the unit presents cognitive, affective, and psychomotor objectives and activities for each lesson. (MDH)

Seventh and eighth grade classes investigated the uses of energy in their school and presented a report to the school board indicating current use and costs, projected future costs, and recommendations. (SD)

A project to tempt students to pose questions, state hypotheses, measure, estimate, compute, and evaluate their answers in terms of a problem they can see and manipulate is described. Selecting landmarks, collecting data, developing a blueprint, interior decoration, and fabrication are among the points discussed. (MNS)

Benefits of Instant Logo are discussed. Activity cards are illustrated and suggestions for teaching the unit and managing the class are given. (MNS)

Activities for a 10-day unit on probability and statistics are described, with preplanning ideas included. Spinners, dice, cards, wheels, and other materials are used in a variety of games. (MNS)

A week-long build-a-city project is described which lets students become familiar with the history of the five Platonic solids (tetrahedron, octahedron, hexahedron, isosahedron, dodecahedron) and then use these solids to create a city using posterboard and construction paper. (MNS)

Tessellations provide an opportunity to incorporate a variety of geometric topics in one unit, allowing students to review shapes and focus on relationships among them. Three activities are described, with illustrations. (MNS)

Described is a four-month social studies unit allowing for the integration of mathematics and language arts in grade one. The unit focuses on the concept of shelter; mathematics emerges as the key investigative tool used to facilitate and broaden the children's view of where they and their classmates live. (MNS)

Presents a unit to review geometric concepts and problem solving by having students work cooperatively to discover geometric shapes constructed from two congruent right triangles obtained from cutting a rectangle along its diagonal. Students report their findings both orally and in writing. (MDH)

Presents a unit developed by the 1991 Oregon Mathematics Teachers of Middle School project in which students investigate the average temperature, precipitation, and snowfall in their town using spreadsheets and graphing packages. Students compare the averages over a period of 30 years to a particular year. (MDH)

Describes a unit designed to integrate mathematics with other curriculum areas by drawing on real-life situations. This unit incorporates nutrition, calculators, and graphing skills to classify items from a grocery receipt and represent the amounts of money spent on each category in different graphs. (MDH)
