The global pandemic has changed the mode of delivering lessons. Adult learners have missed and continue to miss the hands-on learning activity, which is a form of experiential learning. When it comes to teaching three-dimensional, geometric shapes (3D), learners often benefit from handling and manipulating concrete shapes. This study examined the…

International comparative studies of education have shown that the increase in mathematical attainment differs significantly among students in relation to the different school types in which their mathematical foundations were acquired. In tertiary education, the same differences are observed with respect to simple tasks that relate to the subject…

In this research we present the use of some technologies in problem solving activities (at different secondary school grades), aimed at finding a model for a geometric configuration, and representing this model in various ways: through a construction, through a Cartesian graph, etc. The task is part of a teaching experiment, in which students used…

The approach to teaching group theory used in this report was to give students many different kinds of examples of the concept being taught. The functions of models and examples in terms of student preferences and the psychology of the learning experience are discussed. Six representations of the tetrahedral group were developed as test materials.…

A series of laboratory or discovery activity worksheets lead the student to explore the relationship between a given polygon and a figure constructed by rules generated by properties of the given polygon. (JP)

A square lattice is used to generate classroom activities, such as counting the number of squares in a lattice of a given size. (MP)

Activities involving the drawing of kites and figures related to kites are described. (SD)

An activity involving measurement of various parts of a bicycle is described. Sample worksheets are included. (SD)

This activity unit leads students to discover facts related to the maximum area enclosed by figures with given perimeters. Three worksheets are included. (MP)

This study attempts to explain certain difficulties which ninth grade students face in tackling geometrical "problems to prove," by relating them to general and to specific rigidity and cognitive style variables. The results confirm the conceptual analysis of Geometric Rigidity (GR). (MP)

Presents two worksheets that ask students to count and classify the triangles that can be formed with a given total number of toothpicks or a given number of toothpicks for one side of the triangle. A third worksheet asks students to identify patterns observed during the investigations. Provides reproducible worksheets. (MDH)

The algorithms for finding cube roots is approached by slicing a cube. (SD)

Topics for student projects in geometry are discussed; useful references are included. (JT)

The properties of the cube are explored. A set of activities is given that forms the basis of a class project on discovery. (MNS)
