Describes five learning activities for practice of number facts which will aid problems with computation in arithmetic instruction. Stresses importance of elementary students' ability to add, subtract, multiply, and divide, rather than rely on calculators and computers, for higher levels of math. (DST)

Advocated is developing intuitive ideas of limits whenever the opportunity arises in elementary mathematics. Examples are given for geometry, fractions, sequences and series, areas, probability, graphing, and the golden section. (MNS)

The importance of using concrete materials to teach fractions is emphasized. Suggestions for preparing inexpensive sets of such materials are given, with nine activities for their use. (MNS)

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)

A problem is discussed in which students investigate the properties of the perfect triangle. (MNS)

Abundant and deficient positive integers are investigated, with a computer program listed. (MNS)

License plates are used to give students experiences in solving problems, following directions, developing numeracy, and writing number sentences. Four activities for different levels are given on the four worksheets. (MNS)

Children used lunch milk cartons to form a cubic meter, then covered it with construction paper and drew squares to show that it contained one million cubic centimeters. (MNS)

Three games in which the calculator plays an important facilitating role are presented. It promotes a "guess then adjust your guess" strategy. The games are described within the context of elementary, junior high, and secondary classrooms. (MNS)

Exercises are used when beginning work with calculators to help pupils think about what they are doing. Four worksheets are included, with discussion of their objectives. (MNS)

Activities for selecting, naming, matching, recording, and reproducing fractions are presented, using a variety of illustrations and materials. (MNS)

Activities involving estimation of the number of objects in a configuration can motivate students to consider parametric models. (SD)

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

A sequence of activities leading to the concept of Pi is suggested. (DT)

Presented are several variations of a multiplication game which develops probability and statistical concepts while it reinforces students' arithmetic skills. (JP)
