    I wanted to stress that I want the children to learn all the numbers
including Zero. Two of my children know it but it was the tenths digit
(and number) that they learned. This is quite soon, but still not the first

thing to learn.

    I mind the order, not subject. Of course children will learn 0, right
after they have learned 1,2,3,4,5,6,7,8,and 9.

   Another concept that is to be learned is the distinction between the
digit and number.
