Symmetry is found in the visual arts, architecture and design of artefacts since the earliest time. Many natural objects, both organic and inorganic, display symmetry: from microscopic crystals and sub-atomic particles to macro-cosmic galaxies. Today it features strongly in higher mathematics such as Linear and Abstract Algebra, Projective and…

Learners are all different and teachers are all different, so why do we often ignore this reality when trying to explain, or demystify, some aspect of mathematics in the classroom? Enabling learning can be challenging, demanding of creativity, and needy of alternatives if understanding is the real goal. Here the authors offer ideas that are aimed…

Nowadays, many technological means are available to support teaching, such as the interactive whiteboard, class sets of laptop or netbook computers, and high speed internet access. For mathematics education there are advanced software packages for geometry, algebra, calculus, and statistics, which in many cases are available on line at no cost.…

Within the project "Engaging mathematics for all learners", led and funded by the QCA, the mathematics team at the Royal Institution of Great Britain (Ri) looked into how mathematical tasks usually reserved for the "gifted and talented" can be used in the mainstream classroom with a wide range of learners to address core…

Two problem-solving strategies involved in finding the area of a particular square formed on a geoboard are described in detail. (MP)

Develops two-dimensional descriptions of degenerate transformations using elementary matrix algebra. (RS)

Finding the shortest route between two points can be approached by vector methods. Several types of matrices modelling a map of 6 cities are described. (SD)

A series of puzzle-type activities combining arithmetic reasoning and geometric figures is described and illustrated. (SD)
