Ready for 4th Grade?

I've been feeling a bit guilty that I haven't worked with Alex this summer on anything educational so when a math lesson presented itself, I jumped at the chance. Alex had some left-over chicken nuggets from (where else?) Chick-fil-A and she had already eaten two. I asked her if she started with eight and she had already eaten two the day before, how many she had eaten that night. She, being much smarter than me, looked at me and said "all of them!" I couldn't argue with that, she was absolutely right! But, I was hoping she would have said six.
