The Mathenaeum. Exploring number The activities in this section are designed to promote an appreciation of numbers as products, the concepts of factorisation and prime factorisation, and to practice working with fractions. Much use is made of graphical illustrations of number value to help visualise the properties being investigated. Exploring geometry The activities in this section are designed to help in the investigation of properties of triangles, lines, parabolas and general concepts in coordinate geometry. Graphical and algebraic representations are provided where appropriate. By supporting both free and constrained manipulation of curves and objects, families of shapes and curves can be constructed and explored. Exploring algebra The activities in this section are designed to help build an understanding of algebra both as a natural extension of number, and as an efficient way of describing things mathematically.
