Describes an activity in which students deal a deck of cards to 5, then 4, then 3, then 2 players; note the number of cards left over each time; and from this information determine the number of cards in the deck. (MKR)

Describes an activity for making the connection between triangle ratios and graphs of circular functions which helps middle school students understand the concept of a sine curve. (ASK)

This teaching guide contains material, for students in grades 6-9, in which a calculator is used in exploring and developing generalizations about quotient patterns generated from various polygons drawn on a hundred square. Includes suggested procedures and four ready-to-duplicate student worksheets. (JN)

Activities for enhancing students' understanding and interpreting of graphical information is provided. Four worksheets and answers are given. (YP)

Presents an activity, suitable for students in grades 6-12, on generating random numbers. Objectives, equipment needed, list of prerequisite experiences, instructional strategies, and ready-to-copy student worksheets are included. (JN)

Presents a day of activities to encourage students to participate in mathematics. Five contests include poster; model; mathematics puzzle; mathematics problem challenge; and essay. Some student entries and the rules for each contest are described. (MKR)

Presents a lesson that connects basic transformational concepts with transformations on a Cartesian-coordinate system, culminating with the application of matrix operations to perform geometric transformations. Includes reproducible student worksheets and assessment activities. (MKR)

Presents a lesson in which students communicate verbally and in writing to create and describe geometric transformations, develop vocabulary, demonstrate ability to give unambiguous instructions to translate a triangle, form and test conjectures, and create extensions of problems. Includes reproducible student worksheets and questions for…

Presented is an activity which shows how mathematics is used in real life and helps to establish a need for mathematics in students' futures. Adapted from a scavenger-hunt idea, this activity helps students to discover that almost every career makes use of mathematics. (KR)

Presents a series of 5 reproducible worksheets for grade levels 5-10 that provide hands-on activities to help develop the concept of slope. (MDH)

Describes a problem to challenge students as they come back from summer vacation. Working in small groups, students discover Pick's Theorem, the formula to calculate the area of a polygon constructed on a geoboard. A writing assignment evaluates the students' efforts. (MDH)

Presents an argument for using dot paper rather than geoboards at postelementary levels to study perimeter, area, congruence, similarity, and other geometric ideas. Emphasizes need for students to be active learners. (GW)

Described are activities that use a hundred chart to improve student abilities to recognize and describe number patterns, to use variables, to make and informally prove conjectures, and to communicate mathematical ideas to classmates. Included are the directions, four reproducible student sheets, the answers, and extensions. (KR)

Describes an activity shared at an inservice teacher workshop and suitable for middle school in which students predict their ideal weight in kilograms based on tables giving ideal weights for given heights. (MDH)

Describes one unit on analyzing and writing mystery stories in a problem-solving seminar for seventh graders that incorporates the use of television, cooperative learning, and reading and writing in the mathematics class. Provides a sample activity sheet and examples of seventh-grade mystery stories. (Contains 14 references.) (MDH)
