For the icing Beat the butter with half of the icing sugar until it is smooth. Add the rest of the icing sugar and the milk and beat until the mixture is creamy. Now split the mixture into sixths! Add a couple of drops of food colouring to each bowl so you have 6 different colours of icing. You will need to mix some colours to make new ones. When the cake is cool, you can spread the buttercream on top of each layer so that all the layers stick together. Now your fraction cake can be cut into more fractions so that everyone has a piece. What fraction of the whole cake is the blue layer in your piece?
