Amaia often watches the older kids playing board games. Being competitive they tend to shout 'six' when throwing the dice, willing them to land on a six. Amaia, therefore, assumed from fairly small that a die was called a 'six'. She has gone more generic now, deciding 'six' in fact means anything cube-shaped. Consequently, when she's building with blocks, she is often to be found running around asking if anyone has found any more sixes! I guess this is another example of her functional language!
