This paper presents a sequence of computer-based activities aimed at achieving an intuitive understanding of the ideas and concepts underlying the Fundamental Theorem of Algebra. Deductive proofs to support students' empirical investigations are also discussed. (LZ)

Presents a project in which one science class, curious about large numbers, created one million marks on paper. Discusses other concrete representations of one million and other large numbers. (MKR)

Using sequential chains of regular n-gons in a row with one side touching, as for example, one triangle, two triangles, three triangles, and so on, students graph the length of the perimeter versus the number of n-gons and determine the functional relationship for different values of n. (MKR)

Describes data analysis activities for grades three to four and five to six based on popular television commercials. Includes reproducible student worksheets. (MKR)

Presents an activity that involves drawing pictures to collect data, conjecturing a recurrence relation, and solving the relation using geometric series and partial fractions. (MKR)

Presents applications related to African day-names, the sunrise clock, and the Islamic calendar. (MKR)

Describes a school project to choose a mascot in which students learned about sampling and polls while collecting, organizing, and analyzing data. (MKR)

Presents five math activities designed to help students understand fractions, keep students motivated, and help them maintain their math skills. The activities are "What's in a Name?""Fractured Words,""Egyptian Fractions,""More Fractured Fractions,""Name the Parts," and "Timely Device."…

This article encourages hearing individuals in the elementary school community to learn sign language. Suggestions include having students teach students, having family sign classes, incorporating sign instruction throughout the day, giving everyone a name sign, and having schoolwide events in which signing is featured. (DB)

Presents alternative equation-solving procedures that emphasize an examination of the steps or operations necessary to perform a calculation, followed by the inversion of those steps. The approach is especially attractive to students with limited mathematical skills. (Author/MKR)

Presents proofs of some trigonometric identities from a geometric point of view. (MKR)

Provides activities for the study of light as a theme for December, which encompasses Christmas, Hanukkah, and Kwanzaa. Includes science activities and suggested books for children and teachers. (HTH)

Describes two learning activities: (1) high school students design and construct a wind powered monohull vessel to travel a predetermined distance in the least amount of time; and (2) sixth graders learn about energy by doing gas and electric meter reading. (Author/JOW)

Provides insight into the exciting future of robotics. Includes a student quiz and possible student outcomes. (JOW)

Through corporate support, a bird-watching program was implemented at a summer camp for underprivileged New York City children. The program featured oversized flashcards containing color photos and facts about each bird, instruction on use of binoculars, and a hands-on experience in which campers used binoculars to identify bird cards placed in…
