Suggests that teachers use "warm-up" activities to introduce their lessons. Examples of 25 such activities are presented. All of the activities can be modified to meet the needs of particular students. (JN)

Describes two sets of activities designed to stimulate thinking skills and to bring some topological aspects into the mathematics curriculum. One set explores Mobius strips; the other set deals with tori. The activities are suitable for students in fourth through eighth grades. (JN)

Third- and fourth-grade students were introduced to palindromes (numbers that can be read the same both forward and backward). The types of problems that they generated, investigated, and solved are presented. (JN)

Presents activities designed to help children understand the notion of a sample in a homogeneous group, a concept essential to understanding "R times E" problems. Underscores the importance of children's understanding the situation in a problem so that they can solve it. (JN)

Describes activities designed as self-checking tasks involving practice with whole number operations. Materials consist of a set of boards partitioned into 36 squares; sets of 36 sentence/picture cards correspond with each board. A correct sentence or picture is then formed as students correctly perform the necessary mathematical operations. (JN)

First-grade children mastered 72 of 100 addition facts by the middle of the grade, with mastery being defined as a two-second response to a given addition fact. A sequence of activities is presented that serves as an outline of the approach taken. (JN)

Presents a problem-solving activity in which students first guess and then check their answer. Also presents an activity to help students develop skill in understanding the question in a problem and a suggestion to help develop a classroom climate conducive to problem-solving. (JN)

Presents: (1) a computer program which will change a fraction into a decimal; (2) a program in which students supply missing lines to create the output given; and (3) suggestions for adding computer awareness to classrooms, including use of used punch cards and old computer-generated printouts. (JN)

Describes an activity approach for teaching upper elementary school students the concept of angles. In the interdisciplinary activity, students practice reading and drawing angles from 0 to 360 degrees as they simulate the behaviors used to navigate a sailboat. Includes list of equipment needed and procedures used. (JN)

Lists three guidelines for the sound use of manipulatives in teaching geometry. Also describes activities that use manipulatives to teach topics in geometry and measurement and which illustrate the application of the three guidelines. (JN)

Six algebra activities which use manipulative aids are described. The aids can be motivating, multipurpose, and individually manipulated by students. Some of the activities involve students in problem-solving practice and some can be revised to provide for students of differing ability levels. (JN)

Describes an aid designed to reinforce the meaning of one- and two-digit numbers by building a strong bridge between iconic representation of numbers and their various abstract, symbolic representations. Although most suited for first- and second-grade students, it has been used successfully with kindergartners and in remedial work with older…

Describes activities which involve a four-step approach for using manipulative materials to develop some fundamental concepts in probability and statistics while using ideas about fractions, ratios, proportion, and percentages as an integral part of problem-solving investigations. Steps include introducing the model, establishing a recording…

Describes a mathematics enrichment program in which third-grade students become involved with field-day activities, workshops, a song and stunt program, movies, a slumber party, and other events. The program began in school on Friday and continued until parents picked their children up the following day. Program schedule is included. (JN)

Described are graphing activities which can be instrumental in introducing the mathematics concepts of counting, sorting, grouping, and comparing on the primary level. On the intermediate level, these activites can be used to introduce collecting and sorting unorganized data, and creating graphs to represent the data. (Author/TG)
