We regularly use Sumdog in school as a way of revisiting and practising math concepts. The children love earning coins and working their way through the levels, gaining new pets and items for their virtual world. Each child has their own log-in.
We use the Nrich website to promote the learning of mathematics through problem solving. The activities provoke mathematical thinking and the children learn by exploring, noticing and discussing the problems. It is open to use at home and there are regular problems that are waiting to be solved on the website.
