‘Dartboards’ are basically organised collections of numbers. They are very simple to use, easily designed, versatile and can be used with children of any age. They can contain any numbers and, with careful thought, the colours can relate to mathematical concepts you want the children to develop and practice. For example if a set of numbers is entered in the orange band then the yellow outside band could relate to doubling, halving, multiplying by 10, adding 9 etc. and the inner blue band to something different.
