NUMBERS: Figuring out new ways to explain.

We run into a bit of a problem counting down form 60 or 80 etc.  O knows everything that comes before 20 and counting to and from 100 in 10s but the in-between bothers him.

For example, as soon as he reaches 91, he goes back to 99 so with things like '82 - 4' just forget it!  Since we started learning 'add' 'take away' concepts by saying 'going up' ( one , two, three etc steps) or 'going down', now we are going to try some kind of a visual 'up and down steps' ladder from 10 to 100 all inclusive.  Wish us luck! Today's second day doing it!
