Visualization of mathematical relationships enables students to formulate conjectures as well as to search for mathematical arguments to support these conjectures. In this project students are asked to discover the sufficient and necessary condition so that two circles form the circumscribed and inscribed circle of a triangle and investigate how…

Some activities with tangrams and their use for investigating fractions, constructions, and percentages are presented, with worksheets included. (MNS)

Five activity booklets are presented for implementing Project EAGLE, an enrichment program for gifted and talented primary-level children. The first booklet, "Sound," contains four activity pages to accompany teaching of the concept that sound is transmitted through air to the ear. The "Groups 1" booklet provides nine…

Six thematic activity booklets are presented for implementing Project EAGLE, an enrichment program for gifted and talented primary-level children. "Animals 3" introduces endangered animals and locates their home areas on maps or globes, using nine learning activities involving science and creative writing. "Magnets" discusses…

This research investigated the possible impacts of computers on Turkish fourth-grade students geometry scores and further geometric learning. The study used a pretestinterventionposttest experimental design. Results showed that students who did not have computers at home initially had lower geometry scores. However, these differences were…

Six thematic activity booklets are presented for implementing Project EAGLE, an enrichment program for gifted and talented primary-level children. "Animals 2" teaches the concept that animals have a variety of characteristics and attributes, by having students choose an animal, think of a problem the animal might have to solve, picking…

Activities from the "IDEAS" department which appeared in the "Arithmetic Teacher" between 1980 and 1985 were selected for this publication, designed for students in grades 4 through 6. The activities were reprinted just as they originally appeared in the journals. The selections are arranged according to the major topical areas of the curriculum:…

These activities were designed for use at the University of Montana, where they were tested for four quarters in a mathematics for elementary teachers course on informal geometry. They are for use with Apple II-Plus computers with 64K memory or Apple IIe computers and MIT Logo. (Modifications are necessary if the activities are to be used with…

This teacher's guide and student guide are designed to accompany a mathematics textbook that contains supplemental readings, activities, and methods adapted for secondary students who have disabilities and other students with diverse learning needs. The materials are designed to help these students succeed in regular education content courses and…
