Changing the dramatic play area in a child care setting promotes creativity and gives children the chance to experience a place they may never experience in real life. Whenever possible, the children should be involved in the process of changing the area, by moving furniture and exchanging props, as well as brainstorming ideas for changes. The…

Worksheets and instructions are provided for measurement activities using a clinometer and hypsometer. (SD)

A practicum intervention was designed and implemented over an 8-month period for the purpose of enhancing the mathematics-related cognitive and social interaction skills of primary school students in five kindergarten one pre-first, and seven first grade classrooms. Students interacted in group discussions and activities involving interest…

Children in sensorimotor and preoperational stages, as well as at the preschool level, learn fundamental mathematics concepts daily through experiences in the environment. When children enter formal learning environments, they are active, curious, egocentric, and verbal. It is hoped that they will encounter capable teachers who can choose…

Rhythmic gymnastics is an outgrowth of rhythmic and dance gymnastics and promotes good posture, strength, flexibility, balance, and coordination, along with appreciation of music and movement together. The current status of rhythmic gymnastics and its historical development are briefly discussed. Descriptions are given of rhythmic gymnastic…

An activity is suggested which will give junior high school students practice in estimating and measuring in centimeters and millimeters. Three worksheets are given, one of which is a model for making a metric caliper. (LS)

A device is suggested for constructing triangles with the same area and the same perimeter. A proof is given as is a proof of necessary conditions for a special case. The question of congruence of the triangles is left to the reader. (LS)

This article offers a novel way of having students construct models of the five Platonic solids without the use of glue. Patterns and directions for students are provided. (DT)

The relationship between area and perimeter is presented through a series of laboratory-type activities and demonstrations. (SD)

This study focused on (1) the relation or transition between the measurement and partitive settings for division, and (2) the study of these two interpretations in general case where the remainder is not necessarily zero. Ninety-four second-grade pupils from four classrooms (two in each of two schools) were presented, through individual…

An exploratory investigation designed to gain insights into children's mathematical formulation of observed actions upon objects is presented. Eight episodes in which first and second graders were asked to interpret, in terms of number sentences, a sequence of actions with unifix cubes are also presented. Results of analysis of the videotaped…

A guide for using an abacus is accompanied by a heavy-duty paper abacus. The guide includes instruction in how to represent numbers on an abacus as well as in place value, addition, carrying, subtraction, and borrowing. Diagrams are used throughout the guide and a brief English-Spanish vocabulary list specific to the use of the abacus is included.…

The Springs Task measures the ability to conduct controlled experiments, name variables, and criticize variables which are demonstrated to the subject. It provides an operational definition of formal thought. Subjects aged ten to adult can be tested with this instrument, an apparatus-based task administered individually in a 15-minute interview.…
