An activity which involves the drawing of geometric designs on familiar number arrangements (such as the addition and multiplication tables and the hundred chart) is used to help students discover patterns and at the same time maintain computation skills. (DT)

Strategies for winning in the game of NIM are discussed and explained through applying a base 2 representation for the numbers involved. (DT)

Presents a situation in which differential calculus is used with inverse trigonometric tangent functions to maximize an angle measure. A negative distance measure ultimately results, requiring a reconsideration of assumptions inherent in the initial figure. (Author/MKR)

A recreational activity providing practice in computation is described. Examples are provided and the underlying mathematics is analyzed. (DT)

Describes several activities to provide opportunity for the discovery of number patterns and shows the need for care in the descriptions of such patterns. (Author)

The problem of determining the number of squares on a checkerboard is extended to finding the number of rectangles on an n x n board and finding the total numbers of cubes and rectangular solids in an n x n x n cube. (DT)

Three activities and patterns involving the addition table are described, each involving pentagons. (MNS)

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)

Three activities on the right justified multiple triangle are presented. The activities are designed for use in practicing computational skills and for discovering number patterns. (JN)
