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

Suggestions are given concerning the use of the pocket calculator for computations that are too trivial to be processed by a computer but too time-consuming for manual calculation. Several examples from arithmetic, algebra, trigonometry, and calculus are included. (DT)

Lessons are suggested which involve dice in the instruction of various number concepts. Activities are presented under: (1) Early Number Concepts; (2) Meaningful Addition and Subtraction; (3) Place Value Practice; and (4) Extensions for the Intermediate Grades. The primary advantage of dice is their adaptability to student ability levels and…

Two posters that involve digits and number activities designed to provide motivational activities for students are presented. It is thought the posters can be used to introduce some ideas from elementary number theory. Both primary objectives and possible instructional extensions are reviewed. (Author/MP)

A modification to the ancient game of NIM is promoted which can provide a set of games seen as suitable for promoting practice in subtraction and simple strategy formation for a range of pupils in both the primary and secondary grades. The game versions noted are normally for two players. (MP)

Pupil difficulty with understanding mathematical sentences is viewed as a problem with reading comprehension. Suggestions are made for ways to help children over the "missing-addend hurdle." The focus is on an educational game that has been used successfully to get students to focus on the meaning of mathematical sentences. (MP)

Certain properties of lenses provide a physical model of the mathematical concepts of multiplication of integral numbers and of similarity transformations in geometry. Further, they can provide a realistic concrete representation for rules governing multiplication of signed numbers. Suggestions for problems and classroom demonstrations involving…

It is suggested that the reasons for teaching the standard written algorithms for calculations are not out of date. Alternative algorithms, such as mental algorithms, calculators, and nonstandard written methods, are discussed. (MP)

Two problems are presented and discussed as a means of demonstrating that the calculator can play a more important role in the mathematics class than simply as a computational tool. (MP)

A number of mathematical games, tricks and puzzles, are described as a way to make drills for elementary school students as interesting as possible. (MP)

These worksheets will provide students with experiences in identifying largest and smallest single-digit numbers, in writing names for single-digit numbers, in tests of divisibility, and in writing number sentences. (MP)

Three examples are given illustrating the use of the calculator in problems where determining patterns and making conjectures are stressed. (MP)

Presented are two examples of real-life examples that can be used to promote or exemplify concepts of probability and statistics. Details of the calculation of these probabilities are given. (CW)

Measurement experiences can promote and illustrate number work in an intuitively satisfying way. Some current practices that are counterproductive for developing number sense and some alternative strategies that are more constructive are included in discussions of the approximate nature of measurement, realistic measurement, and work with rational…

Discusses weak links in children's developing power in counting. Presents assessment information for mathematics curriculum planning and activities embedding the subskills of counting into daily routines. (MKR)
