Just to let you know, I think many of your comments on reading decimals are
excellent. A good balance of algorithm and understanding. The only
good way for a student to learn the "count the numbers after the
decimal point" algorithm is to notice it him/her/itself. To teach
it to them first is to "protect" them from learning the concept. The
comment I made about how to say 45/100 was just for fun; I hope you
didn't take it as an attack. (Although I do think that ideally our
kids should learn all of those ways of looking at that expression).

Another way that just occurred to me to say that is "four five slash
one zero zero." That would be pretty much analogous to point four
five--just reading the characters.

Well, this was going to be a private communication, but I guess I
will just post it to the list since a little content seems to have
leaked into it.
