ICT has the capability to transform the way pupils understand and learn mathematics. When used with sensitivity and careful planning, it can act as a catalyst, contributing to a stimulating classroom climate which can bring mathematics alive. This paper takes a fresh and critical look at the use of ICT in mathematics teaching in Primary schools, considering some of the key benefits that ICT can offer, as well as the difficulties which can arise. It is time to look carefully again at the challenging, yet stimulating and exciting opportunities that these technologies present for teachers.
