These worksheets represent gameboards designed to provide practice in estimation using a calculator. Worksheets are presented for estimation in addition, sums and differences, products, and quotients. (MP)

Ways in which classroom calculators enriched, supplemented, supported, and motivated the regular sixth-grade mathematics program are discussed. (DT)

Ways elementary school teachers might use calculators to help students are noted. A total of nine activities, listed under place value, computation, and estimation, are provided to assist the classroom instructor in effectively employing calculators. (MP)

A calculator activity, described as a bingo game, emphasizes speedy calculations as well as problem solving. (JT)

Calculator activities for grade 1 are presented. Included are introductory activities, such as keying and finding patterns, and skill lessons, with such topics as ordering number, greater than and less than, estimation, and problem solving included. (MNS)

Several problems that can be used with calculators are provided. Teaching tips and references are included. (MNS)

A method is explained for using the calculator to determine the day of the week on which any given date falls. (DT)

Calculators are seen to shift the student focus in problem-solving situations from "how to do it" to "what to do," by keeping computation from standing in the way when pupils write or solve problems. (MP)

Developing numerical relationships with calculators is emphasized. Calculators furnish some needed support for students as they investigate the value of fractions as the numerators or denominators change. An example with Logo programing for computers is also included. (MNS)

This section has four topics: (1) sample mathematical competency problems for Indiana Elementary Teachers circa 1920; (2) an unusual problem suitable for calculators; (3) a unique way for teaching rounding off numbers; and (4) student construction of problems that create words on calculator displays when they are turned upside down. (MP)

Several learning activities and games designed to stimulate and challenge mathematically gifted kindergarten, first-, and second-grade pupils are outlined. Many of the ideas presented can be adapted to other levels. (MP)

Four worksheets are included, providing practice in estimation, computation, pattern recognition, and problem solving involving calculator use. (MNS)

Three methods for using four-function, counting calculators for developing understanding of the meaning of square roots and operations on whole and rational numbers are described. (MP)

What is number sense, why it is important, how it is taught, and how it is measured are each discussed. Examples with concrete materials, calculators, and pattern recognition are included. (MNS)

Activities are suggested for using the hand calculator as a complement to any mathematics program. The activities focus on developing skills for using the calculator, exploring basic arithmetic operations, understanding algorithms, mental calculation and estimation, and problem solving. (DT)
