This paper summarizes the developmental activities in mathematics conducted at the first grade level. Two instructional units of "Developing Mathematical Processes" were taught. The instructional units are described through a description of the activities that were tried, an explanation of evaluation procedures, and a report of the results of each…

The arithmetic portion of the Developing Mathematical Processes (DMP) program, as it applies to children of ages 5 to 8, is described in some detail. The terminal objective of the number program of the primary segment of DMP is the ability of the child to correctly write, read and validate mathematical sentences of the form A = B plus or minus X.…

Two methods of adding columns of single digits were compared in terms of the speed and accuracy with which sums are produced. The direct method (successive addition) was found to be better than the method of looking for combinations which sum to ten. (SD)

An activity similar to magic squares is described. (SD)

A case is made for a comprehensive curriculum that includes strong competencies with not only number ideas and computation, but also with other mathematical topics such as geometry, statistics, probability, and estimation. (MP)

The objective of this activity is to provide a calculator experience developing and reinforcing the concept of order of operations. Three worksheets are provided that are suitable for reproduction for classroom use. Teacher instructions and answers are provided. (MP)

This discussion of the mathematical potential of classroom events gives many examples of incidents that can be used for learning about topics such as one-to-one correspondence, counting, sets, ordering, time, fractions, money, shape, estimation, measuring, volume, area, number operations, and graphs. (MP)

The concept of prime factorization is discussed and two rules are developed: one for finding the number of divisors of a number and the other for finding the sum of the divisors. (MP)

Math can be basic and motivational at the same time. Help your students discover numbers and enjoy them. (Editor)

A method is discussed for learning the multiplication tables that avoid repeating tables everyday or memorizing a large body of facts at the same time. (MN)

An instructional sequence in which number lines and beads are used to illustrate addition and subtraction of directed numbers is described. (SD)

In a thesis written for the Doctor of Arts in Mathematics, the connection between Euclid's algorithm and continued fractions is developed and extended to n dimensions. Applications to computer sciences are noted. (SD)

An activity that offers computational practice, pattern recognition, and the formulation of generalizations is described. (JT)

A computer program which produces a print-out of one million items is given in elementary Fortran. Observations of the print-out help students relate to such a large-number concept. (JT)

The authors illustrate the magnitude and application of the concept of a "googol" (ten raised to the one hundred power) in searching for entities that exist in such number. (MN)
