In the winter of 1965, an experimental course in Elementary Number Theory was presented to a 6th grade class in the Hosmer School, Watertown, Massachusetts. Prior to the introduction of the present material, students had been exposed in class to such topics from the University of Illinois Arithmetic Project as lattices, number lines, frame…

Using various aspects of mathematical structure as unifying concepts is stressed. Specific examples are given based on the concept of equivalent fractions and on the addition property of equality. (LS)

Allowing students to examine different ways of performing an operation is suggested as a means of increasing their understanding. (MP)

A teacher discusses his attempt to analyze his pupil's difficulties with arithmetic by looking at the component parts of each operation. (MP)

Three game activities are detailed. Informal work with addition and subtraction on a number line and graphing concepts are achieved with two simple dice games, and the distribution of monetary tokens is used to illustrate the division algorithm. (JP)

This curriculum guide for grades K-6 is the first volume of a two-part series. It is meant to provide an ordered sequence of mathematical concepts from which teachers may organize an arithmetic program allowing for individual student progress with the greatest amount of individual attention. Each topic is arranged into levels based on the topic's…

The Minnesota School Mathematics and Science Teaching (MINNEMAST) Project is characterized by its emphasis on the coordination of mathematics and science in the elementary school curriculum. Units are planned to provide children with activities in which they learn various concepts from both subject areas. Each subject is used to support and…
