Kai can immediately tell mummy “10 and 8, which is greater?” “3 and 5, which is bigger?”
With this greater concept well in mind, it is easier for Kai to move on to mental addition by automatically putting the bigger number in his mind/mouth and add on the other number by counting on with fingers. Now Kai is using Montessori golden beads for addition and subtraction.
Kai and jiejie also use the materials for other play...
