A detailed account is given of the activities of children during their free-choice class periods for two days. (MP)

Presents the rationale behind the need to teach the metric system and includes a description of the most important metric units. The stages through which children pass as they develop an understanding of the process of measurement are discussed. Bibliographic material is included. (EB)

The role of language in learning mathematics is discussed. A variety of philosophical essays and research findings are cited as the author argues for the importance of language as a tool for understanding and creativity in mathematics. (SD)

A multiplication algorithm based on a perfect square is described. (SD)

Stresses the value of encouraging students to question the results of both obvious and the less obvious scientific activities. A simple science activity built on chemical reactions. (EB)

The use of dice and dominoes in the classroom is discussed as leading from counting activities to pattern recognition and discovery learning. (MP)

Activities suitable for use with primary school students are described. The author offers advice concerning expectations of the students, use of the vocabulary of probability, integration of activities with other classroom work, and related topics. (SD)

The objective were to explore some of the ways in which the calculator can be used and to determine the effects. Areas covered are: computation, mathematics readiness, problem solving, and discovery learning. (MP)

Playing with number patterns can lead students to discover some divisibility tests. (JT)

Having students find and cut out of graph paper the 12 pentominoes can provide an enjoyable exercise in perception, discovery, and double checking. The pentominoes can then be used to illustrate informally several geometric concepts. (SD)

Reports on a part of a report on primary schools in England. States that science instruction tends to be superficial, and that the teaching and the content require more planning. (GA)

A description is given of a lesson on two digit multiplication with nine-year olds that utilizes trial and error and partitioning of the problem in a discovery type approach. (MN)

An approach is illustrated that introduces selected models of addition and subtraction to students who have previously learned a model for either operation. (JT)

Three activities for involving students in projects that incorporate writing, drawing and recording their findings are included. The discovery approach is emphasized. (EB)
