Mamas words:
Liane bought over a pile of money for him to sort and count.
He did wonderful sorting them, then counting them into piles of $100. Keeping track of the piles counted and figuring out the total amount was a difficult task. When he got it right, he fumbled with accepting his thought process and had to recount each pile for accuracy. Then he reconfigured the piles.
He did seem to enjoy himself and he did a wonderful job staying on task. Though the end result was very difficult to decipher, he accomplished the task!
She asked him to count all of the money and tell her how much was there.
