Approaching Infinity

... from the preschooler side of things.

Snippet of conversation between Anna and I, as I try to reinforce the concepts of value, larger, and smaller:
Me: So, Anna, if I asked you if you want 11 Hershey's Kisses or 12 Hershey's Kisses, which would you choose?
Anna: [giggling] 12!

She likes this game. Eventually, we get to her choosing between 28 Hershey's Kisses and 29 Hershey's Kisses. She makes the correct choice, and then asks me why 29 is the. biggest. number.

I tell her (in my best algebra teacher voice) that there is no 'biggest number', that we can always think of a number that is one larger than the one we have. Feeling that I am on solid intellectual footing here (trust me: this is nothing compared to the 'heaven' discussions we have had), I proceed with my "Well, what's a bigger number than 29? Thirty!" and so on and so on examples.

After a few of these she looks at me:
"Yeah, Mommy, ok, but what number is the roof?"

Which I thought was a pretty cool way of putting it.
