This article shows how an inexpensive calculator can be used advantageously to determine repeating decimals. Even the decimal representations of numbers, such as one-seventeenth and one-nineteenth, can be easily computed. Many examples are given, and some theoretical discussion is included. (Author/MP)

The objective of this activity is to provide a calculator experience developing and reinforcing the concept of order of operations. Three worksheets are provided that are suitable for reproduction for classroom use. Teacher instructions and answers are provided. (MP)

Chapter two of the book, "Problem Solving with Calculators,"is presented. Topics covered include parts of a problem, steps in problem solving, guessing, and methods of calculation. (MP)

The authors present a computational skills laboratory exercise for ecology conscious students. (MN)

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)

Support of the need for more emphasis on mental arithmetic in the classroom is given. Classroom methods and activities for developing skill in mental arithmetic are included. (MN)

Three worksheets dealing with number triangles are given. Exercises are designed to lead students to discover number patterns within the triangles. (MP)

The purpose of this activity book is to provide fun while learning and reinforcing mathematics in the following categories: (1) mathematical concepts and applications; (2) mathematical computations; (3) geometry; and (4) mathematics for daily living. A gameboard and playing cards are provided in this book. A die, pawns, and a container for the…
