Slavonic Abacus for Android mobile phones and tablets. The Slavonic Abacus is a brilliant teaching aid for pupils who are struggling to master basic mathematical skills. What makes it so special is the unusual colouring of the beads which allow the visualisation of numbers as patterns. This makes the abacus ideal for those pupils (such as dyslexics) who may have strong spatial skills. The abacus will be of interest to teachers who are following the Wave 3 maths intervention programme.
