9 layered birthday cake made from timber. Eeach layer is a different colour and sliced into a different fraction size. The cake shows whole, halves, thirds, quarters, fifths, sixths, eighths, tenths and twelfths with 16 candles surrounding. High quality, 51 piece and 20cm in diameter. Very handy for clearly showing how a whole can be broken into various fractions, and also for showing equivalent fractions.
