Math For Lunch?

We work with the kids each day on skills that they need to improve upon or to help them learn the next educational step in a subject. Just before lunch, Jeremy decided to practice using scissors to cut paper. Beth and I were going to work on simple addition. She seemed very willing, so I set us up at the table near Jeremy so I could keep an eye on him at the same time.

As this wasn't the first time, or the second either, that we were working addition, I decided it was time to show the written math sentence while still using the little rocks to complete the problem. Prior to this, we had only used the rocks. We did two problems and as we started into the third, Beth tells me she doesn't want to do math, she wants to cut.

Knowing only where one pair of scissors were, and Jeremy had them, I told her she'd need to wait and that we needed to finish the problems we had. She immediately started to whine, held her stomach and said "I'm full of this."

Math for lunch, anyone?
