Forty-three preschoolers learned the concept of one-to-one correspondence by matched discovery, expository, or observational learning. The groups did not differ on short-term recall and near transfer, but the discovery group excelled on far transfer and delayed recall. The effect of guided discovery on broader learning outcomes was also discussed.…

Capturing junior high school students' interest in computation is the aim. Three activities are described in which computation acts as a needed tool within a problem-solving context. (MN)

Patterns resulting from polygonal numbers are explored, with examples of triangular, square, pentagonal, rectangular, and other numbers. Tables and formulas to be developed are included. (MNS)

Three worksheets are given that use calculators to free students from computational restrictions and allow them to focus on the recognition of patterns and the application of numeration concepts in the development of their estimation skills. (MNS)

Presents activities that have been used successfully in leading students from concrete experiences through pictorial and symbolic representations of important numeration concepts and patterns, including place value, multiples, and rounding. Each activity includes concept or skill fostered, list of materials needed, recommended grade level, and…

Presents an activity, suitable for students in grades 6-12, on generating random numbers. Objectives, equipment needed, list of prerequisite experiences, instructional strategies, and ready-to-copy student worksheets are included. (JN)

The probability of winning the contest was analyzed, with the mathematical solution and a computer simulation given. A flowchart and computer program are both included. (MNS)

Activities are presented to give students a picture of decimal concepts of tenths and hundredths. Three models (linear, regional, and value) are described, followed by four activities. (MNS)

Beginning with a simple computer program to teach a fundamental concept and building in small increments is suggested. For the topic of repeated operations, three activities, an extension, and some problems are given. (MNS)

Drawing floor plans for an apartment is used as the basis for giving students practice in applying the concepts of ratio, fractions, and scale. (DT)

A mathematics unit which introduces number concepts through the use of patterns. All activities are based on the formation of patterns involving blocks or tiles of two colors. (RP)

Properties of the harmonic number triangle are listed, and ways of generating the elements of harmonic triangles are described. (MNS)

This manipulative learning aid is featured as a tool that allows a teacher to build upon the recognition of number patterns to teach basic mathematical understanding. The activities provide a means to help children refine, develop, and extend their understanding of the number system. (MP)

Ways to use styrofoam egg cartons and plastic eggs to enhance mathematics instruction are detailed. These materials are viewed as inexpensive, colorful, and easy to obtain. Suggestions for using them to teach concepts related to whole numbers and fractions are provided. (MP)

Four activities and four manipulative materials for teaching place value are discussed. (MP)
