The author argues that when behavioral objectives are properly used they can provide direction for learning, and that they need not be restrictive. (SD)

Several activities are described for students at different elementary grade levels. Some involve estimation of quantities, and others include reasoning about permutations and combinations. (SD)

Ways to use a calculator as an integral part of mathematics instruction in existing curricula are provided. Activities are proposed that will help children think about mathematics rather than merely push buttons. (MN)

A series of learning activities used in grades one and two to teach number conservation and arithmetic are presented in detail. The activity sequence is based on working with one-to-one correspondences for a lengthy period before introducing arithmetic operation. The author claims the approach is very successful. (SD)

A method of using pegboards to illustrate addition of whole numbers is described. (SD)

The examples given in this article served as models for the basic principles of "Peer-Mediated Instruction," the focus of six years of classroom research at Teachers College, Columbia University and one approach to the buddy-system of teaching. (Author/RK)

Four worksheets are provided for developing decimal concepts. For levels 1-2, dollars and cents is the focus; for levels 4-5, tenths and hundredths; for levels 5-7, comparing and ordering decimals; and for levels 6-8, estimating with decimals. Teaching suggestions are included. (MNS)

Described are activities for thinking through patterns using toothpicks, paper strips, wooden cubes, and people patterns; thinking with attribute items such as geocards, namestrips, and treasures; and thinking with geometric materials such as geoboards and dot paper, cubes, and simple puzzle pieces. (MNS)

The use of a variety of models to develop number concepts is advocated. Four models are discussed, with illustrations: the cardinal number of a set, Cuisenaire rods, the number line, and the Papy Minicomputer. (MNS)

Using manipulative materials and pictures is considered valuable, but the need to use models appropriate for individual children is stressed. Suggestions for using well-structured physical space are given. (MNS)

Provides activities (and program listings) related to a Mendelian genetics experiment, Tetranacci numbers, and Pascal loops. Also suggests using the computer and spreadsheets to plan the production of a school yearbook. (JN)

Three activities and patterns involving the addition table are described, each involving pentagons. (MNS)

The use of real (professional) bingo sheets for a math bingo game is described. The game can be adapted to many levels of learning for a variety of concepts by using different calls. A sample of these calls is given. (MNS)

Research on the usefulness of calculators in mathematics instruction is cited, and some activities using calculators to develop skills with reading numbers, counting, basic facts, multiplication and division, problem solving, estimation, percentages, decimals, patterns, probability, and games are described. (MNS)

This teaching guide consists of two short lessons: (1)"Centuries and Millennia"; and (2) "Days, Weeks, Months and Years." The first lesson shows major religious and secular concerns that, in various ages, combined to produce the calendar that now indicates the beginning of "a new millennium." It is specifically…
