Hi!
(Oh, hypatia posted while I was typing.
I'm going to go ahead and post what I'd typed anyway.

From what I remember from the Doman book, he suggests doing words in sets of 5. You start with the first set of 5 the first day (showing the set 3 times a day for 5 days, then taking out one word and replacing it with a new one). You can then start adding more sets, up to 5 sets a day. That would be 25 words a day. He also suggests not doing them all in a row, but at least 30 min. apart (I think that was the timing).
I'm not sure why she didn't show that she had learned the numbers.
