Re: Saying Decimal Numbers

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 fivejust 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.
