Numbers 11-20

So we continue to work on numbers 11-20, but it has been hit or miss.  So today I took a new approach, the way she learned the letters - we focused on just two of the numbers.  We did the numbers 12 and 13.  (I picked 12 because when I showed her the 2, she said, 'That's not 12!" So I figured she was ripe for 12).  I made a card with the number 2 on it and one with the number 12 on it, and then I played a game of "shuffling" them behind my back, putting them in front of her, and asking, "Which is the number 12?"  and/or "Which is the number 2?"  Once she had done that correctly a number of times, we added two more cards, with the numbers 3 and 13.  She started getting bored and wanting to play with her Elmo, and so we taught Elmo about the numbers, which she really got into.  I think this approach might have worked better, although she was still misidentifying 3 vs 13 at the end.
